Fantastic Windmill (FW) is a static web site generator: it reads content from a set of source files, applies a presentation template to them and saves the output as a set of static HTML files. The main difference with respect to other generators is that FW relies on a very small set of concepts to provide the same functionality. As a matter of fact, if you know how to write web pages in PHP, then setting up a static web site using FW should be very, very easy. Cloning and tweaking this repository might be all you need.
For more information, please refer to Fantastic Windmill's documentation --which, by the way, is probably the shortest of all static web site generators. Enjoy!
