Run as service

While I second Larry's suggestion on getting the 
Hammond/Robinson book, you don't need to have this
kind of thing running as a service unless you really
want it running when you're logged off. (Which I doubt
as having popup messages doesn't make lots of sense).
You can use Irmen de Jong's Kronos, coupled with the 
pywin32 extensions (URLs below) to have something like 
the following script in your Startup folder, run under 
pythonw.exe. It will popup message boxes when you want, 
but otherwise won't get in the way. If you really want 
something in the systray then certainly look for examples 
of that kind of code. But it's not strictly necessary. 
Neither do you need Kronos: you could roll your own 
time.sleep loop. But why bother, when someone's already 
done the job?

<code>

import kronos
import win32ui
import win32con

def do_reminder ():
  if win32ui.MessageBox ("Continue?", "Reminder", win32con.MB_YESNO) ==
win32con.IDNO:
    raise KeyboardInterrupt

#
# Interrupt every 5 minutes
#
INTERVAL_SECS = 60 * 5

s = kronos.Scheduler ()
s.addIntervalTask (
  action = do_reminder,
  taskname = "Reminder",
  initialdelay = 0,
  interval = INTERVAL_SECS,
  processmethod = s.PM_SEQUENTIAL,
  actionargs = []
)
s.start ()

</code>
