I played with something some time ago but not exactly to build a website. I've made a website for presentations, blogs, articles where the content is stored in the URL. To preserve anonymity I decided not to allow login with nostr but rather creating random nostr account stored in your local storage. Visitor of the site can respond to the article with kind1 notes.
It's a bit odd and not that pretty but if you plan to put online something secret (or not) it's a quick solution :)
www.snofl.com and go from there.
