It is not possible to do 100% nicely without extending the window
manager specification (http://www.freedesktop.org) and getting the
window manager to do it for you. All you can do is move the toolbar
when you get a GdkEventConfigure on the main window. But there are
cases where this will screw up, and it will have an annoying "lag" to
it (user will see the main window move, then the toolbar).  Also,
you'll have to rely on the somewhat unreliable
gdk_window_get_frame_extents().

If the toolbar has a frame, you need to use window gravity to align it
properly. i.e. for a toolbar on the left as in your diagram, you would
set WestGravity. See gtk_window_move() documentation.
