Cheers, thanks for the links. I've done a bit more googling since posting and discovered I don't need carbide at all, Nokia have something called Qt Creator, which would probably be more suitable for beginners (could be wrong). It's available to download from http://qt.nokia.com/developer

Also, I thought Qt, was it's own programming language, but it seems it's C++. So what is Qt? Is it a derivative language? Or some kind of API set that can be called/used by C++? please forgive my ignorance, as mentioned I'm coming from a VBA background which I appreciate is very different from C++.
