I just think cron isn't that bad but, sure, a front-end would be highly appreciated by many people.
I'm dropping in this comment just to tell you that "crontab -e" is a better way to edit your crontab: the command is shorter and it handles crontab restarting for you.
Another "crontip": instead of adding 12 entries in order to run the same command each five minutes, you could simply use a "*/5 * * * *" instead.
As an example, experiment adding the following line to your crontab:
*/2 * * * * date "cron command run on: +%Y%m%d-%H:%M" >> ~/cronlog.log
Then you go take a coffe, return and issue a "crontab -e" and comment out that line, otherwise it would fill your hard drive with test-junk. Finally, a "cat ~/cronlog.log" will show the results.
So your crontab could look like this, instead:
# Special 5-minute-interval job
*/5 * * * * /usr/local/sbin/sched5 1> /dev/null
Have fun.
