Choosing between WPF, wxWidgets, Win32 API and MFC

Question

Imagine you are on Windows 7 and you have to write a GUI for a GRAPHIC application, (like a terrain editor, mesh viewer ..) which involves a great use of DirectX and OpenGL (so written in native C++). If your goal is a multi-platform software then you should go for wxWidgets, but imagine you're doing a Windows' only app...what would your choice be? and why?

I'm supposing that the application would work on both XP and Vista/7 and obviously in the WPF case the UI will be managed, but it will call native functions by a C++/CLI proxy-like class ( will "bouncing" from managed-native and native-managed cause performance issues? ).

Answer 1

RAD Studio can also make the job

• Enhanced in 2010! VCL (Visual Component Library) for rapidly building Microsoft Windows applications now includes seamless Windows 7 support, and graceful fallback compatibility with Windows Vista, XP, and 2000
• Enhanced in 2010! Windows Vista and Windows 7 API headers to fully exploit the latest Windows capabilities
• New in 2010! Support for Windows 7 Direct2D API

you can also make WPF with Delphi Prism and wxWidgets with twinforms

Answer 2

If you are comfortable with your C++ skills, I recommend WTL. It is very lightweight and results in lean machine code. The Windows version of Google Chrome was written with WTL.
