You can achieve that goal using a jsni communication channel.

I don't know what kind of communication do you need between the framework
and the widgets, but you can event share Overlay objects.

I'll do it this way: your framework declare a global javascript function and
when a widget is loaded it calls that function with all the information you
need. And as I said if you declare gwt Overlays you will be able to easily
share complex information.
