Quickest/easiest way to create a toolbar?

hi, i'm trying to create a toolbar for my cocoa app. i think i came across a site with open source code that you could easily insert and customise for your project, but i can't find it now.

if that site doesn't exist anymore, does anyone have any good sources for toolbars? some of the resources i've found (e.g. macdevcentre) seem really complicated.
