I've been searching for something similar tonight and found this jQuery plugin which seems that could help you out. You can directly generate .ics files "on the fly" with it which should be good for Google, Outlook, iCal and Yahoo.

I haven't had a chance to test it myself though, but plan to do it in the next days. However HTH!
