GTK+ Now avaiilable for Mac

GTK+ is a cross platform toolkit for creating mainly Linux and Unix GUI applications as well as 32 and 64 bit Windows. It was originally for the GIMP ( GNU Image Manipulation Program) in 1997 and on Linux you can use it from C++, C# and other languages. It's used in GNOME, one of the Linux desktops, openMoko (the open mobile phone) as well as the Maemo (Nokia's Internet framework) and for the Mac.

GTK+ is built upon the GLib library which started life as part of GTK+ but exists separately and holds all the non GUI code. I see it as more of a framework; given that it has a type system GType, an object system GObject, memory pools, threads, string utilities etc.

If you are looking for a toolkit that supports themes, is thread safe, is built on objects, has support for internationalization including bidirectional text, accessibility and well documented then GTK+ ticks all those boxes. If you like widgets you'll find that GTK+ offers a lot. A permanent link to the Mac GTK is now in the C code library.
