I don't think that's going to work the way you expect. One big problem
is that a process running from cron can't directly access your X server
so it can't send GUI notices.

I think you're going to need to create some kind of server (running in
your X sessions when you start them) and client (running from cron)
which tries to notify the server and handles the shutdown process.
