But the up front cost of using something like Jekyll is about fifteen minutes of work. Plus you can find a lot of free templates online that make your basic site not look awful.
I know I've spent hours trying to get Ruby setup and figuring our why bundler install failed, so disagree with your "fifteen minutes" comment. Maybe in the best case scenario.
Throwing together a small static website with a few pages, in my experience, is one of those situations.
