Na you'd be best to use colors or if you can get some kind of Java wrapper to just modify the applet directly like Java bots do.
As for SendMessage, that API is tricky in the sense that you'd have to keep your bot up as the focused window (it would not be minimizable).
Overall it's a complicated project, and you'd be best to just make a script for an existing bot that does it.
