Marcel,

I have the same issue in mplayerplug-in in that I cannot use a gtk_plug_new in 
gtk2 (although it works in gtk1). I worked around it with this code (many 
hours of bashing around to get something working, and it turns out to be 
simple). A GTK_WINDOW_POPUP is an undecorated window.

        GtkWidget *gtkwidget;

        gtkwidget = gtk_window_new(GTK_WINDOW_POPUP);

        XReparentWindow(GDK_WINDOW_XDISPLAY(gtkwidget->window),
                        GDK_WINDOW_XWINDOW(gtkwidget->window), x_window, 0,0);

        gtk_widget_map(gtkwidget);


        Where "x_window" is a X window id.
