There are far too many options for Windows GUI programming, so we
probably need a bit more information about any constraints that
are important to you.
For example:
- do you specifically want something that works well with D? or
are you open to other languages?
- are you just wanting to learn desktop programming in general?
(Like the concepts involved) Or do you have a specific thing you
want to create?
I would personally suggest Delphi to somebody who wants to write
Windows desktop apps and learn about event-driven development,
howeverrr the language (Object Pascal) is insufferably archaic
compared to something like D. But it is definitely the cleanest,
least-overwhelming method of writing native Win32 applications
for somebody with no prior experience.
Then there's all the modern Microsoft stuff (WPF/XAML/WinRT/etc),
but you pretty much have to use either .NET or C++ for that.
