Gtk# is a C# binding for the Gtk toolkit (www.gtk.org). The target is the 2.0 platform, and no plans are currently in place to backport to 1.2. The effort essentially boils down to an exercise in PInvoke against the C dynamic libraries. It may end up being slow as hell, but we'll see when we get there and adjust accordingly. The "Hello World" application in the sample directory has been executed on Win32 using the Gtk and associated binaries provided by the Gimp Win32 porting project. Links to these binaries can be found on the Gtk Homepage.
