CentOS - Feb 2010 - Display a warning message at a certain time ?

Hi,

I'm currently installing a CentOS 5 desktop as a public internet access 
point. The machine shuts down every day automatically at 22:30. Is there 
a way I can display a message in GNOME at 22:15 warning the user that 
the machine will shutdown in 15 minutes ?

Any suggestions ?

write or wall will work with open terminal windows - but shutdown offers 
the option to send such a message itself with a grace period before the 
actual shutdown.  It gets trickier if you want to pop up a new window on 
all open window managers.

I believe the shutdown command automagically generates warning.  I would
*guess* that GNOME would have some applet that monitors these sorts of
warnings and creates popups.
