It is very diffcult to say which one is best without knowing what u want to do..
There r lot of options ..It also depends upon Your webserver and also on your budget.
If you want some very simple features with almost zero cost then you can go for PHP or Perl,
If you want to host it in Window Platform (with IIS Server) then you can go for ASP or ASP.NET
If your requirement is very complex or complicated then you can go for JSP or Java Servelets..
Do try to explain your requirements, may be i can help you more...
