Thanks for that suggestion - the other problem I am having is being able 
to get at the button.

I have used        
        popup = self.applet.get_popup_component()
        popup.connect('ui-event', self.ui_callback)
        applet.setup_menu(xml_menu, ...)
where the radio buttons are defined in xml_menu.
