I wrote my own tool here because I too had little interest in complexity of some of the larger generators: https://github.com/Ceasar/staticjinja. It's just 129 lines of code (https://github.com/Ceasar/staticjinja/blob/master/staticjinj...) and so far I've used it to build three sites with the ease I was hoping for. Might be what you're looking for, and at least, you should be able to edit it to fit your needs.
