you should export the Continue and Cancel button widgets so your 
application can connect to the "clicked" signal of the buttons. If you 
want a slightly cleaner solution you could also make your dialogs real 
widgets derived from GtkDialog (or whatever is appropriate) and have 
them emit "continue" and "cancel" signals.
