We still use win32 with a light weight C++ abstraction we wrote ourselves (like MFC but better). It's not really complicated or hard.

MFC+Win32+WinForms are equivalent with different wrappers. So is WPF/WinRT/Silverlight so that's actually only two tech platforms.

I agree that going with Win32 + your own wrapper is probably best in the long run.

As far as WPF/WinRT/Silverlight go, they are different enough that it's hard to exchange any code between them or port from to another.
