Create a toplevel window:

        toplevel = w = gtk_window_new(GTK_WINDOW_POPUP);
        gtk_widget_realize(w);
        gdk_window_set_decorations(w->window, 0);
        gdk_window_set_functions(w->window, 0);
        gtk_widget_show(w);

That creates a window with no WM decorations.

Next create a GtkDrawingArea widget and put it into the toplevel
window:

        da = w = gtk_drawing_area_new();
        gtk_drawing_area_size(GTK_DRAWING_AREA(w), 48, 48);
        gtk_widget_add_events(
            w,
            GDK_EXPOSURE_MASK
        );
        gtk_signal_connect(
            GTK_OBJECT(w), "expose_event",
            GTK_SIGNAL_FUNC(MyDrawFunction), NULL
        );
        gtk_container_add(GTK_CONTAINER(toplevel), w);
        gtk_widget_show(w);


Your MyDrawFunction() function should draw whatever you want
it to look like.

To make it a special shape (not rectangular) use:

        gtk_widget_shape_combine_mask()

On both the toplevel window and the GtkDrawingArea.
