Specifically, I use the Node Webkit project which is an app runtime built on top of Chromium and Node.js. A pretty neat way to get effectively free cross-platform support on Windows, OSX, and Linux.

I'm not sure how Sublime is getting their cross platform support. I've been interested in it for a while though, so I hope someone chimes in.

If I needed to make something that ran ON the user's hardware Python or C would be my choices.
