Creating a Tab-Bar Application?

I love the idea of tab bar apps in iOS - as an iOS dev, a lot my apps make use of tab bars for navigation.

Is it possible to use Tab Bars in Mac OSX development, or are we limited to toolbars and other "act-a-like" solutions?

 

So NSTabView functions the same, but has it's own little window, correct?

When building with it, is it similar to working with a UITabBar for iOS? IE, I create views, and they are associated to their respective tab in the NSTabView?

Also, as I'm using the tabs on the bottom of the window, what can I do in terms of a thin toolbar, similar to iPhoto '09's? I'd like a small area to stick extra buttons, and that would be perfect, as well as make the application look more polished.
