Your site is currently not viewable. You said that you were new to web design, and although Dreamweaver is a fantastic platform to work from, without basic knowledge of programming you could get yourself in trouble real quick.
Without a basic building block to get you going, a design from scratch can be both a challenge, and frustrating. However, with a successful build it can be very rewarding. Dreamweaver is a great tool and fantastic for on the fly updates, but programming is also involved. Depending on the type of platform you desire it could be quick but most likely you will want a more robust platform shortly after.
