Just for fun i removed kpty (this was the only bit which was guaranteed not to work with win32.
And downloaded and compiled it on qt4.4.3-win32-mingw.
Fired it up :o !! i saw the ui... well not too much surprise there, its qt after all,
But then gave it path for msysgit binary and that worked as well.... Hurra!!!
Tested setting up user name/email, works. Tested with teamgit repo almost everything i tried worked.
Tested 'send patch by email', heck it even fired up outlook express.
Damn QT is the best toolkit i have used ever.
Patches are upstream, you can compile current teamgit on windows
