If you just create the dialog and set up its signal handlers, you  
return immediately, and control returns (eventually) to the main  
loop.  It sounds like what you want is to block in that function, and  
not return from your select function until the user answers the  
dialog.  To do this, you need to do something like

    $response = $dialog->run;
    $dialog->destroy;
    return $response eq 'yes';

Gtk2::Dialog::run() starts another main loop, and will stop that main  
loop when the user activates a response.

Whether it is actually a good idea to block on a modal dialog in a  
tree selection handler is another question entirely.
