Cocoa: create iTunes / stuff like sidebar with Xcode 4.0

Does anyone know how I can create iTunes / Things like Sidebar with Xcode 4.0 (Screenshot: http://i.stack.imgur.com/7uvCt.png )? I am new to this and tried to play with NSSplitView and NSTableView, but I have no idea how to get the “Name” (for example, “Erfassen” or “Fokussieren”) and the Numbers with numbers (“8”) in Eingang, “4” in Heute).

Thank you so much!
