Is it Possible to send messages to all the individuals on a event on facebook with a script?

Say that I am attending a event on facebook, and I want to send a message to all the other people attending individually even those I am not friends with on Facebook. I want to send the same message, but it is a bit of a time stealing thing send the message to everybody one at a time.

Is it possible to make a script or a program that can do that for me?
