Installable Web Apps - Google Code. There you can find some background information on how to convert web applications into installable web applications or hosted apps. This allows you to use Chrome as a runtime for applications that behave very similarly to regular applications - Amazon's online Kindle is a great example. Programming is done in JavaScript, which is much less intimidating than it was a few years ago. As Packaged Apps, you can also do everything that Chrome Extensions can do (and can go beyond the scope of regular web applications).
