Freewebs does support HTML and CSS, and I agree with Mikhail in that these are the two languages you need to create a nice looking website. HTML on its own will probably not get you anywhere, but as soon as you combine that with CSS, you can create some pretty awesome stuff.
HTML is quite easy to learn, and CSS is very easy if you use a good program like Dreamweaver, which fills in all the attributes and things for you. Despite this, both languages can take a lot of time to grasp, whether you know every single HTML tag or CSS property by heart or not. If you plan on learning either of the two languages, the earlier you start, the better.
