http://www.gamedev.net/reference/list.asp?categoryid=76#218 gamedev has a useful series of articles on creating a scripting language, probably a good first step before moving onto building a compiler (requires a huge amount of understanding of the underlying mechanisms of computers).
1. That's a crap thread title. You obviously didn't read the pre-filled title. 2. Why reinvent wheels by making yuor own programming language. As if there's not enough out there already. 3. If you really do want to go down that hard core route, this probably isn't the best forum to ask your questions. Most of us are webmasters and a lot of us hate or are scared of coding.
Is this a serious question? If you have to ask this, there is no way you are knowledgeable enough to actually design and construct a new language compiler. Theoretically, you can build a compiler with just about any existing language that produces executable code, but an HLA (high level language) will make the job more difficult. Most language compilers are written in C or assembly.
Very confused. Do you want to use VB , VC or C#? Do you want to develop GUI application or web application?
