Java and .NET are the Cobol of today. And, as for C++, give Objective C a whirl first. Steve did. It's behind that X in OS X.
If you sincerely want to avoid Cobol, you should really should go back to 1958. If the parens put you off, consider JavaScript, Lua, Ruby, Python, Clojure, Scala.
I like Scala a lot. Eventually the Java language won’t even be the language of choice people will write for JVMs. I like Ruby as a language as well.
