MyCoolButton is a very easy to use web graphic application that will help you make a cool little web 2.0 logo in about 4 steps. You can setup size, color, font and icon.

You can paint your button with preloaded web 2.0 icons or upload your personal icon and customize the font of the text inserted. The website is ajax based so no reloads, just click on apply changes and it will show you exactly how your logo will look. You can download the logo in png file format.
