I worked on a similar problem! (But much, much narrower and less ambitious.) It's designed for games like dating sims. It takes a spec, written mostly as dialogue, and converts it to gamemaker code. I wrote it to help some friends avoid tedious manual translation, which apparently saved them a lot of time.
