wxWidgets is free and open source. You don't have to worry about wxWidgets' vendor going broke. You will always have access to the source code.
wxWidgets supports more compilers than probably any other framework. All popular Windows C++ compilers are supported, and on Windows you can use the Cygwin or Mingw32 free compilers. Even the 16-bit versions of Visual C++ and Borland C++ can be used. On Windows, makefiles are provided, with project files for VC++ 5 and above. Just about all known Unix C++ compilers are supported, for the Motif and GTK platforms.
wxWidgets allows you to target:
Linux/Unix with the GTK+ toolkit (or plain X11, or Motif)
MacOS
Windows Vista
Windows XP
Windows ME
Windows 98
Windows 95
Windows NT
Windows CE
Windows 2K
So, you don't have to worry that your development investment will be made obsolete.
