Automated update of google (or other) calander from an online form

Hi there I'd like someone to offer me a solution to enable me to automatically populate "event" data inputted from an online form (either a google form or HTML) into an calendar (google or otherwise)? The "online" data capture form would only need to be a simple one containing the following fields: Date: Location: Start Time: Description: Account Number: Contact Email: Contact Phone Number: My idea is that I email out the link to this "online" form and then as people complete the form and submit the results this automatically updates an online calendar. At the minute it's becoming an increasingly time consuming job for me to "sift" through received emails and then manually update a calendar several times a day. Plus of course the fact that I'm re-typing information could always lead to the possibility of human error. High security isn't a great concern as the link will only be emailed out to around 100 "trusted" people and in turn each person will only perhaps be adding 20-30 events per year. I am of course open to suggestions on any alternative ways of achieving a similar result, The simpler and smaller the cost the better as this work is being undertaken for a charitable institution. Thanks George
