Whats a good way to...?

Question

Greetings everyone. I´m currently working on a IRC client using Visual Studio .NET(2003) and have encounterd somewhat of a problem. I got stuck when I was trying to make the "Settings"-form. The question I´m asking is what´s a good way to..well redo or change the layout and adding/or removing textboxes etc. A bad explanation? lets see if this is a better one. Take alook at the link that follows: http://ptha.mine.nu/~supertank/example.jpg I want whatever is in the red area to change when clicking on either Server, Channel, Setting etc. And again my question is. Whats a good way to do this, any special technique? (any more questions? feel free to ask)
