If the site you are creating is for "friends & family" then by all means use Frames. But if the site is for anything more than that then you should take into account that Frames are not the way to go.
There are a number of reasons for this, the chief being security, but Frames are no longer considered to be an acceptable design technique.
If you want to create a website using good design techniques then you should be looking at using CSS. You use Dreamweaver, which fully supports CSS. Once you have used CSS to design a site you will never want to use any other technique.
