404 error pages?

[wheee!]

I'm a new user to the boards here so I apologize if this has come up before but I want to put up a page on my website that people see instead of the generic error page that IE returns. Is it HTML/Java code or do I have to learn another programing language to do it?

Thanks for any help..
