I'm a professional web master. Here's a site i did that works on Amiga's and was done on an Amiga 1200. It was quite a few years ago.
http://www.trep4.com/amicheats/It was done entirely in html using Ced. The ability to do search and replace across all the files at once was a major sanity saver in updating the site.
There's no reason it couldn't be done again on an A1200 with Ced. However, i'd do it with php pulling the content from a mySQL database.
