you mean like programming languages? C, C+, Java, Python, Bash, objective C, cocoa, vb, .net, php, html, and so forth?
I am not sure if there is a really high demand for such a thing, and most likely any coding anyone will do here will be on a scripting level. If you are developing applications you either do so with colleagues at work or with an open source community.
might be cool to add a section for it though
