Perhaps you could just use a modal window:
        gtk_grab_add (window)  gtk1.2
which by definition grabs focus, so everything else
is blocked. Your dialog window could have only
a label showing a message, something as: 

"time for cofee :-), mouse and keyboard disabled :-("

After some minutes you just remove this
window and the user has control again.
If you want (and you know the times)
you can even add a progress
bar in continous mode, so the user
knows how much time has to wait.

If you do this, you must block also 
the delete_event signal in the window,
so users cannot close it with the
WM decoration tools, Close, etc...
(no way to block the Kill though)

This is simple and gives users a clue.
