Make use of google calendar into my website?

I have a website that has some register users, now I want to provide calendar service for them. I am considering using google calendar to ease my development work, the requirement should be:

1) Google calendar needs to support non google users, because my website users are not google users开发者_开发知识库 2) Support provision from my website, that means my website can create calendar account for my users. ...

For simplicity, my objective is create one account for all the registered users, and manupulate the data in the calendar on behave of my user.

Is it possible?
