ASP or ASP.net are good programming languages. For myself I like Unix, Linux, C, C++
Java script and good old time DOs.
But you are buliding a website here? Probably a mix of boring HTML and Java would be best. There are ways of twining codes together because all programming codes are linked together in one way or another, by necessity.
ASP is not bad but, plan on taking probably a good year to fully appreciate and master. Programming is like a book with many chapters, chapter one would be, say unix and so forth. But they all come from the same book so does HTML.
I have just told you something that should get your mind going.
