GTK+/GTKmm

GTK+ and GTKmm are the C and C++ interfaces (respectively) to another toolkit for building graphical user interfaces. It is popular in the Gimp and Gnome development communities. There is a beta native version of the GTK+ 2.x toolkits available for Mac OS X. If you already have a C or C++ application or are considering building one, GTK+ lets you build applications that run natively in Mac OS X as well as Linux and Windows.

Information about Gtk-MacOSX (an implementation of the GTK+ 2.x toolkit) is available at http://developer.imendio.com/projects/gtk-macosx.

These toolkits do not run on top of X11 in Mac OS X, but are source-code–compatible with the equivalent X11 implementations.
