You get the principle but I would like to do something better than using
callbacks for events... Or at least use an event layer between GUI and proc
that do the things...
I think XML2GUI should be a relatively simple thing to do isn't it ?
The hard work is to begin the spec for the XML and after that we could create
a Tk engine to have a base of work...
