HTML Reservation Form to Google Calendar

We currently have a static HTML reservation form that uses PHP to email the result to a nominated email address.

The form includes
Name
Phone
Email
Location* (Dropdown list of 2 locations)
Date
Time
Comment/Message

Could we have this data also go to a nominated Google calendar. Either a script at the user end, server end or using Googles API.

Calendar Entry:
The name field should be “Reservation: Name” and go in the name part.
The location field should go in the Location part.
All the other fields should go in the body.

We currently use Google Apps for Business.
