In UK, enquire of Grey Matter Ltd for legacy versions of Delphi (Delphi 2009 and later) that may be available.
GO-Global® publishes any Windows programs on the Web. And Web application development in Delphi Professional is available using IntraWeb to run Delphi Windows programs in any Web browser at any location.
List of Delphi books is here, and in Downloads, Delphi Windows Programming PDF's include Mastering Delphi 7 (1000+ pages) and Object Pascal Handbook (October 2014 Draft) by Marco Cantù.
For choosing programming languages, part of recommendation from a UK schools exams board (AQA) is: 'Pascal/Delphi is highly recommended because it was designed specifically to teach programming and problem solving... Its event-driven forms-based object Pascal manifestation, Delphi, has excellent support for a range of applications from networking through graphics to databases. Delphi is still rated as the world’s best RAD system and is used extensively throughout the world for commercial application development.'
Start out with Free Pascal compiler (download here) together with tutorials like Learn Pascal tutorial and books, like Essential Pascal (version 2 PDF- download here).
Graphic at left (click to enlarge) shows Free Pascal IDE that is practically same as original Borland Turbo Pascal from which Delphi developed for Windows programming.
For Windows programs, Delphi can represent real-world objects as advanced Records offering straightforward approach to programming with objects, to mirror mental model of the application. Argument here is Delphi is good for modeling in the sense of 'the representation, often mathematical, of a process, concept, or operation of a system, often implemented by a computer program.'
Example for download here is Delphi desktop app, sample to model the elevator algorithm: simple rules for elevator (British - lift) stopping at floors:
Continue traveling in the same direction while there are remaining requests in that same direction.
If there are no further requests in that direction, then stop and become idle, or change direction if there are requests in the opposite direction.
This may be interesting to extent it shows how a lift never arrives at upper floors while busy going down below.

Intraweb (IW), is VCL for the Web in Delphi. Two ways of seeing things. One, IW is a gee-whiz technology, extending Delphi to provide a complete development system for advanced Web Apps (see Bob Swart - IW Development). Two, immediate use of IW is limited to providing a set of components, for use in IW forms, that substitute for Delphi VCL common components, with advantage of doing Delphi Win32 application programming yet being able to publish Web Apps with the look and feel of Windows in any web browser.
IW components (on tool palette) that are counterparts of VCL components are listed in on-line RAD Studio Help.
Example of IW programming is IWtriangleapp - download the Delphi source files here. And see programming notes IWTriangleAppNotes.pdf.
Installation of IW on EC2
EC2 Windows 2003 demo of IntraWeb (IW) StandAlone Server. Graphic-1 (click to enlarge, arrow keys to index) - Demo IWtriangle folder extracted from IWTriangleAppServer.zip downloaded on EC2 (remote desktop); IWTriangleAppServer.zip is here.
Graphic-2 - IWtriangleapp.exe opened on remote desktop, working as an application server, listening on port 8888 (default).
Graphic-3 - EC2 Security Group for running Instance - Port 8888 (default) added to allow connection with IW standalone server.
Trial of IW on EC2
Graphic-1 (click to enlarge, arrow keys to index) - Firefox browser on client machine addressed to public IP of running instance, port 8888 so as to connect with IW standalone server. Graphic-1 shows IW logon dialog - password is admin/admin. Graphic-2 shows triangle geometry app in browser window.
IW Authorised Users and File Operations
Graphic-3 - With admin logon, menu Settings > List Users is available to show dialog for administrator to add user names and passwords. With authorised user logon (List Users not available), user directory is created if not present in docs folder shown in graphic-4. File menu - file save (graphic-5), file open and file delete - files saved in user directories (graphic-4).
IW on Android
Graphic at left (click to enlarge) - Low-cost ZTPad (Android 4.0.3) - Firefox browser addressed to IW server - user logged on and Triangle app displayed and operable with IW server Device Simulation set to PDA. Touch screen performance proven, including on-screen keyboard in response to number input selection.
Installation of GO-Global for Windows (GGW) host on EC2.
