Yes, it is possible. You'll need to have the rsvp_event extended permission for the user. And you can use both php and/or javasctipt to perform this action.

Taken from Event - A connection in the faecbook graph api...

To mark an event as "attending" you make call to this url : https://graph.facebook.com/EVENT_ID/attending
