What did the programs you say you have written for so long do?
Seems hard to believe you have not encountered reading and writing
files etc.

Programming for Windows is basically no different than programming for
say Linux or any other operating system, the same code applies but the
compiler will translate to the proper syntax to call the operating
system without you having to bother....

In order to do graphic programming you should look at FPC sidekick
Lazarus, which handles Rapid Application Development by letting you
design your forms interactively. And it does not limit the target to
Windows, same code can be used for Linux and other operating systems.

Programming:

Message box:
ShowMessage('Message text to show');

File handling:
var
 F: file;
FileName: string;
begin
 FileName := <filename on disk>;
 AssignFile(F, Filename);
 Rewrite(F);
 Writeln(F, 'text to write');
 CloseFile(F);
end;

etc, etc, etc
