I think that all you need to do is to fix the switch/case statement in
the delete_event callback.  If this callback returns FALSE then the
destroy_event callback will be called and your program will quit.  So
you would do something like:

gtk_widget_show_all (dialog);

gint result = gtk_dialog_run (GTK_DIALOG (dialog));
switch (result) {
        case GTK_RESPONSE_ACCEPT:
                /* Return FALSE and have destroy_event called */
                return FALSE;
                break;
        default:
                /* Close the dialog and return to the main window */
                gtk_widget_destroy (dialog);
}

return TRUE;

In your program, note the comments at the start and end of the
delete_event callback, and in the main function where you connect the
signal handlers.
