dremaweaver would basically code your website for you, which means you dont have to code it (and in some people's eyes this would be a good point), but the bad point of it is it uses very messy coding, which is prone to not displaying correctly and can become very annoying.
A much better way would be to learn html, i learnt it within a few hours and soon had my website built. Plus, if you learn html the 'proper' way then you will soon become very skilled, whereas with dreamweaver progress is slow. I highly recommend
W3Schools for a very good html tutorial. It's also got a good css one as well
