Design, yes and no. Used an existing template as a base and heavily customized it. Built it, yes (completely by myself).
Uses FlourishLib (http://flourishlib.com/) as programming framework, jQuery for front-end magic and iconfinder.net for the cute icons all around.
BTW, This particular app has been in development for last 5 months. Since Jan 2009, I was prototyping few different things (see http://www.wingify.com/labs.php) and finally built Visual Website Optimizer.
