Tabbed interface on options page for plugin

Hi

I’m developing a plugin for a client, and ordinarily I would just have all parts on one page, but for this one they have requested tabs.

Basically the plugin allows them to upload custom header images on a site I am developing for them, one tab will list the images already uploaded, the second tab will allow them to do the actual upload from the Admin section of their site.

Is there already a built-in style and library to allow this, or would I have to write one?

Thanks in advance
