A C++ develpoper currently wokring on a cross-platform OpenGL mobile app

My area of greatest experience is C++; but i have some knowledge of Java, Python, C# (but I've never touched ASP), and PHP/CSS/JS. I have an keen interest in furthering my knowledge of the web languages and really want to learn where to start with ASP. I have touched briefly on VB.Net and Prolog many years ago.
