why someone would embedd a python interpreter but write the gui code some 
some other language escapes me, but well ;-)

right. you need to create an import lib for gcc. thats done with pexports 
and dlltool:

also remember to use -mno-cygwin for gcc if you want to make native win32 
apps with cygwin.
