Is there a Windows version of GTK+? [GTK 2.x]

The Win32 port of GTK+ is maintained concurrently with the Xwindows version in CVS. As such it is a supported architecture.

The Win32 port has been predominately done by Tor Lillqvist. Tor maintains some information on GTK+ and GIMP for Windows.

There is a pre-compiled, easy-to-install version of GTK+ for windows on the Dropline GTK+ site.
