[Users] Grid placement utility?

Just curious: Has anyone developed a user-friendly utility for placing refined grids for Carpet?

I'm imagining writing a little "drawing" program which will allow the user to draw rectangles to place grids, and then it would generate the CarpetRegrid::coordinates lines for a parameter file.

But I don't want to reinvent the wheel if someone's already done something similar.

Thanks, Scott
