If you're looking for something dead simple, I'd suggest Mithril. The API is tiny, but powerful, and will give you the tools you need to create reactive views that update to state changes.
The major downside to using highly unopinionated frameworks like Mithril is that the burden of project organization is on you. But since this is a personal project that you can use to learn FE development, I think it would be a good fit.
