You need gdk_window_shape_combine_region() or gdk_window_shape_combine_mask():

http://developer.gnome.org/doc/API/2.0/gdk/gdk-Windows.html#gdk-window-shape-combine-mask

Use one of these on yout toplevel window widget after showing it. Also
gtk_window_set_decorated() to remove the title bar and size widgets
(but before showing it).
