Assuming you use Date to represent the time you want to fire the alert, schedule a custom Callable task in a ScheduledExecutorService.
Ths code would look like this:
myScheculer.schedule(alertTime.getTime() - System.currentTimeMillis(), new AlertTask());
In the AlertTask implementation, use JOptionPane.showMessage() to pop the notification.

Yes you can if you prefer. No big difference. See also http://stackoverflow.com/questions/409932 and http://stackoverflow.com/questions/637110 – ddimitrov Jun 09 '10 at 12:43
