Question

Is i possible to trigger a workflow from the creation of an event in iCal
Or is is possible to create a workflow to ad events to an iCal calendar which then triggers the workflow or is combined with the ad events workflow.

Hmm, nope. Not that I'm aware of. Very few apps allow you to hook scripts directly to user activity. Finder* is a notable exception. iCal's "publish" feature has the ability to auto-update after user activity, but you'll either need dot mac accounts or your own webdav server to get that working.
I'd re-consider the idea of triggering a periodic workflow with iCal. That way if the computer is shut down or asleep, iCal will wait to run the workflow at its next opportunity. You could hide the unsightly repeating events in a second calendar so they're out of the way.
The next best thing is to write a faceless AppleScript application with a long-duration idle handler. The user would simply add it to their login items in System Preferences. This would also resume its cycle after sleep or shutdown.
Yet another option is to write an AppleScript that can register itself in the crontab. This has the advantage of running at a predictable time. If you're careful, you can even set the script to wake up or power on the computer as necessary.
* Folder action scripts can be triggered when files are created, moved, or deleted, but not when they're merely updated. This probably rules out much of iCal's activities in ~/library/application support/ical/.
