wxWidgets is a cross-platform toolkit, you can get it at: http://www.wxwidgets.org/downloads/

To be able to compile, you should compile wxwidgets in advance with release unicode, copy setup.h from include\wx\msw to include\wx.

To almost sucessfully compile, I had to change multiboxclient and server setting in Visual Studio/Project/Properties/Configuration Properties/C/C++/Code Generation/Runtime Library to Multi-threaded DLL (/MD) and add the wxWidgets path to Library files and Include files dir at Visual Studio/Tools/Options/Projects and Solutions/VC++ Directiories
