The easiest way is to have a cron script that runs once a day, with
root provileges, and calls "apt-get update". Then, your notifier could
be as simple as:

apt-get -s upgrade | grep "^[0-9]* upgr" | cut -d " " -f 1

which will give the number of packages that would be upgraded, and
does not require root. But remember: the check should be performed
only once every "apt-get update", because the result does not change
if you don't update the list of available packages.
