Adobe® AIR™ is a runtime environment that lets you use your HTML, CSS and JavaScript skills to make desktop applications as well as web applications. You can also use Flex® and Flash®. There is an SDK that comes with a debugger. I tried it out last night and after looking through the readme file and messing around with things, I was able to run a simple calculator that I built with HTML, CSS, and JavaScript. Go to the marketplace to check out other AIR applications .
