if you have no photoshop skills and want it to be presentable, consider blogger or anything else similar. you won't go far with just html; at least i think it'll be a nightmare to maintain once it gets past 10 pages.
most common tool for building websites is dreamweaver. if you don't know that already, i wouldn't recommend building one on your own.
if you do go the building route and want to implement a CMS, consider Cushy (
http://www.cushycms.com/). never used it myself, but seems easy enough to implement; expect spending some time learning it though.
