As ukgimp said, there are no magic shortcuts to SEO, read around. The best place to start is Brett's Successful Site in 12 Months with Google Alone [webmasterworld.com], followed by browsing around the Google Forum's library [webmasterworld.com]
There are two reasons why I focus on Google: For many of us it is the main source of SE traffic, and in general sites optimized for Google do well in other SEs.
Never underestimate the power of a <H1><H2> and <P> in the right place.
There's about a ton of reasons why this could be a very bad idea. For some cases it might not be, but i really don't think this path should be your first choice - there are almost always alternatives that are more efficient and have lower risk.
I doubt if this is really what you need, otherwise you would not have posted this question i believe. In stead, i think you mean something like the W3C validator, only for SEO - such a service does not really exist.

Stick around, read these forums (especially Brett's 12 month guide as mentioned above).
You will then have all the knowledge you need to make DreamWeaver (or any other html page production software) produce perfectly SEO'd pages.
It's really very very simple.
