Mill Tapping G code Generator

Greetings, I like your tapping G code generator, we are looking at purchasing a cnc machine to do electrical panel backplates and I am looking at your G code generator. a couple of questions:
does it only run in linux, and if so, what linux software do you use, and also can you run linux on a virtual machine to make it work, and once completed, can you download into the cnc machine. Thank you for assistance - Bruce
