Making a Computer program to output serial data to an arduino?

      I am making an underwater ROV, like a remote controlled submarine, and I am looking for a way to control it.  All of the commands are set up to run off of serial commands going to the on board arduino.  This is what I would like to know: Is there an easy way to send custom serial data over a computers USB port, controlled by some sort of virtual controller

I like the Processing IDE, it's a very good complement to Arduino. In fact, I think up to version 2.2, the Processing IDE was built on the same code base as the arduino IDE, they look and function almost identically.
