Yes, GTK+ doesn't support this directly, nor does Glade.  Nor should
they, in my opinion.  It adds unnecessary complexity that only a few UI
designers would use.

The way I would implement such functionality is to define a common
widget map callback for the group that registers the widgets in a list. 
Add the callback to each widget. Then use the list to mark the widgets
insensitive or sensitive, according to the UI design requirements.

Two other alternatives;

(a) if the goal is to disable almost everything, consider modal dialog
boxes,

(b) if chunks of things are disabled, write something that recursively
marks children of a widget as insensitive.
