Website building programs don't give sites a high quality look - you get that from actually writing the site (which means actually learning how to write a site).
Dreamweaver? If I didn't know better, I'd swear it was a cruel joke that Adobe perpetrated on a computer-illiterate public - professionals don't use it. If you want something heavyweight (like a Sherman tank to go shopping with - Dreamweaver is just an armor-plated Humvee), use Aptana Studio. It makes Dreamweaver look like a child's toy, it's free, and it's supported by the community.
Or download Notepad Plus, learn website development, download XAMPP to check what you design, and you have all you need for free.
