GtkD is a D binding and OO wrapper of Gtk+ and is released on the LGPL license.

New in this Release:
* wraps GTK+ 2.16.x series api (and relative libraries: glib, cairo, pango, etc.)
* Mac OSX support
* Support for DMD 2.020 and newer.

On OSX GtkD uses the Quartz port of GTK (http://www.gtk-osx.org/) by default, if you must use the X11 version build GtkD with -version=darwinX11

GtkD 1.2 is now available, get it from dsource:
