Google apps booking

I want an online booking script that sends booking information direct to a google apps calendar. The user sees a caledar and pick a date and time, enter name phone number, email adress, number of persons, what to eat, etc and get a booking confirmation on sms or email. Then the script send this information to the google apps calendar. It will be used in resturante to manage online booking of tables. It has to be simple and easy to intergrate in websites, and must be easy t o translate.
