Livecode. It's a high level scripting language that compiles into executables for every platform. They're almost done with the HTML5 version, which will compile into an executable for the browser. It's friendly enough that I taught myself and got my prototype built for all the major desktops. I'm working on an associated website now and I don't even have to learn PHP because I can keep using Livecode for web scripting as long as Livecode Server is installed. So, basically, learn Livecode and replace a half dozen other languages.
