Considering purchasing

So I've been using Hero Lab for YEARS now to run Mutants & Masterminds, and just today noticed this GM Authoring Kit. It sounds very interesting, but I'm wondering just how easy it is to use. From the description, it sounds extremely versatile, but I'm worried there might be a steep learning curve, and I'm not all that technically-minded.

Also, are you able to use the GM Authoring Kit to modify other games that you have a license for? I've got an idea for a homebrew game I'd like to start working on, using the World of Darkness game mechanics as a basis.
