Certainly something that could be done. It really depends on the functionality you want it to have. Making a simple C, VB or Java program that edits a few text files is not so hard. The problem really comes from the fact that you need someone who can do that, understands the format of the files and is willing to spend the time doing it and changing the format is a subsequent patch effects it.

I may look into it myself, but don't expect me to overcome my terminal laziness anytime soon.
