Using toolbar & views on Cocoa

Hi,

I'm getting started with Mac apps development and trying to figure out some things.

I want to create an app with tabs like Selectable Toolbar from BWToolkit (I try it but still has lots of bugs). And when I click one of its buttons, I want to display a different view.

What are the classes that I need to use? The Interface Builder toolbar component can have such behavior? Is there any example on how to switch between views?
