I agree fully with Mike, the best web design (which is essentially a variation on programming) is best done by hand coding. The great thing is that if you are just starting out, you can get straight into CSS, there are many handy guides and layouts ready available to help you. Such as the well known
W3Schools Online Web Tutorials website. Personally I prefer Dreamweaver for editing / creating websites and web based programming. If you need any pointers feel free to ask.
