Automated software for sending Instant Messages

I have a basic project that I need complete and I do not have a lot of funds for this project. I use MySpace Instant Messenger: [login to view URL] and it does not have a SDK or API for it. This is what I would like to do: Create a program that will auto send messages to my friends. It opens the GUI, clicks "send instant message", inserts my friends username, inserts message, and sends message to my friends. The user names will be pulled from a .txt file, and so will the message. Let me know if this is possible, and if this is possible please explain how. I am standing by right now to go for the lowest / most knowledgeable bidder.
