GTK+ Quartz is a project to port GTK+ to Mac OS X natively, using Quartz, the powerful graphics system that is at the heart of the Mac OS X graphics and windowing environment.

Currently the plan is to do this by using the Cocoa environment. This will involve much work at the GDK level of GTK+. Initially, the plan is just to do a straight port of the X Window System backend, but then integrate GTK+ better with the OS over time.

Oh, and please note that this site is under construction :-)
