It’s in beta at the moment, but it works. My previous attempts to compile and run the native port never worked out too well, but a little testing on it (just gtk-demo) makes it seem like I should be able to run most GTK+ applications without too much pain.

I mostly look forward to a version of Gimp being linked against this framework. Current builds for OSX include everything, are a fairly large, and of course depend on X11.
