What should I use..... I have an Excell spreadsheet that I put together and am considering putting it together in some language.

What are all the differences in C, C++, Visual C.

Where do I start?

If you are conversant with any of these languages already, I think you should go for VC++. If not then let me tell you that these languages have a longer learning curve than some of the other languages like VB.
Exploring a bit of office programming is going help you anyways.
