I don't want to tread on anybody's toes here but suffice to say you've just been given an excellent and complete HTML page - just paste the code into a .html plain text file, put the text from one of your pages in place of the random stuff and then view it in a web browser. You may be amazed at how simple this coding lark is, especially for a simple layout like yours. You wouldn't even need to use Dreamweaver, just a plain text editor will do the job. I find that Dreamweaver can be counter-productive sometimes and is not a good tool to learn code with, it's main strength is in creating and updating websites quickly.

The next step would be to read some of the beginner tutorials in these forums, they've helped me a lot!
