Google apps booking2

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 "iframe", and must be easy to translate. NO PAYMENT OR MILSTONES before 100 % complete and easy for me to use and edit/update information. The customer kan chose how many tables, food type date...etc. and the recive confirmation email with booking number, and the booking details are going in the restourants google mail calendar. It must aslo be limitasjons on the booking if the booking is full of any kind.
