Seems to me you want to create a GdkPixmap backing store, draw to that
with Gdk drawing primitives (arc, line, point, rectangle) with the
proper colors and fill, then create a GtkDrawingArea widget.  Set up the
expose event to draw the GdkPixmap to the GtkDrawingArea's window.

See http://www.gtk.org/tutorial/x2491.html and also see the source code
to the Gtk example program, scribble.
