What you get when you pay for an account is an empty site -- nothing in it at all. It's up to you what you want to put in it. One way is to "roll your own" custom website, either programming HTML and PHP by hand, or using some sort of website builder (Lunarpage's builder, or a commercially available one such as Dreamweaver). Or, if what you want is a WordPress site, you simply install WordPress from the control panel, and let it do the rest. I'm not familiar with this themesgenerator thing, but it sounds like it helps you to build WordPress themes. If so, you could run it after WordPress installation to generate a new theme for you, and install it.
