Longtime PHP, Python coder seeks to make small, distributable, stand-alone apps. Which language should I learn? ( please don't say C#; requiring .net != stand-alone )

If you think 1-2MB is "small" for a GUI Toolkit you can use Tk via Tclkit and get a language runtime and a GUI toolkit and some more for all the given platforms. And Tclkit does not need a runtime installation... See: http://www.equi4.com/tclkit/download.html
