For the commandline users out there...
I use sendxmpp to send me messages (in fact, I have a little wrapper
script "msg" that sends it to me). It's on all my systems, and just sends me
a Jabber message (Google Chat, for instance).
And of course, there are a zillion ways to schedule events, from crontab
to at to simply using sleep. For instance:
echo msg Go pick up Sarah | at 17:00
sleep 4h ; msg "It's been four hours -- have you done the dishes?"
...and of course the ultra flexability of a modern crontab for periodic
tasks. It just pops up as a instant message. You can also run it on inbound
emails (depending on your email program), or just as an alert that something
has finished.
dosomething ; msg Something is done.

There are quite a few web solutions that should mail your actions to
you. www.rememberthemilk.com seems to have a great following.

It sounds like you want to run your own, in which case I don't have
any solution.
However, I've been using www.iWantSandy.com for quite awhile and like
it very much and it is free (and has been reliable for me).
FWIW
