How to create tabbed menus with Wordpress

I came across a Wordpress page at http://ift.tt/1Btwo1O that has a tabbed menu. I'm not a Wordpress guy and I wondered how hard this was to do in WordPress. I have the "WordPress - the missing manual" book and didn't see anything like it there.

Is there a widget or plugin that sets this up to make it easy?

I'm not asking for the code to do this. Is it simple? (Possible answers: "Yes, see Widget A or Plugin A or B" or, "No, you have to do it with custom HTML.")

Thanks for any information.
