The site you showed is a basic html site with the QTVR inserted.
Dreamweaver is a good way to start so I would visit the www.adobe.com site and do some of the tutorials to learn how to get started with Dreamweaver.

Or you can pop over to our Beginner Resources
which has very useful links on how to begin with xhtml/html and css.

I wish there were an easy answer to this but there isn't. If time is short, you may want to consider hiring.
