Richkoi, are you wanting more options in your Dreamweaver?
In your font selection drop down box, at the bottom is a choice "edit fonts list".

If you click this, you can add fonts that are installed on your windows. It lists them all there.

I like using Microsoft sans serif, Lucidia, monospace, Tahoma, Comic sans serif etc.

Is this what you are looking for?

If you like php~pro's excelleny idea, I have scripts, php and javascript that will do the 'stylesheet switch' by user selection.

Or the OS detection script is easy enough to retrieve a stylesheet and save the setting with a cookie.
