Need help with a simple GUI window!!!

Hi im new here so i dont know if im doing the right thing pasting my code into the message frame instead of upploading it in a file...
Im a newbee at GUI programming in windows.
My compiler that is MS visual c++ error code when im trying to compile is:
winxconsole.cpp(116) : error C2440: '=' : cannot convert from 'void *' to 'struct HBRUSH__ *'
Conversion from 'void*' to pointer to non-'void' requires an explicit cast

Need help with this plz help me!
