You would simply duplicate the main loop. Now, depending on what you
want, there are several ways to do it.
     1. set (on the X11 level) the CreateNotifyMask event on the root
        window to get events whenever windows are created. Problem is
        that you may not get the event as the window manager may have
        overridden the default behavior in order to put a frame around
        windows.
     2. If you just want application windows, you can have a look at the
        properties of each window. For an example, have a look at the
        taskmanager applet of gnome.
