How do I get a process list (in a popup button), and then when the user selects the application, can I hide/kill/minimize/quit the application?

That could be a very long pop-up menu. (Instruments demonstrates this quite well.) You might consider listing the processes in a table view instead. – Peter Hosey Jun 30 '11 at 09:13

-[NSWorkspace runningApplications] will give you an NSArray of NSRunningApplication instances representing currently-running processes. I'm not exactly sure what causes a program to be excluded from that list, but it does include any application that the user has launched from the Finder. It also includes a couple of things (the Finder itself, and the loginwindow process) that you don't want to mess with, as well as faceless applications.
You can filter those out using filteredArrayWithPredicate:; the objects you want to keep have an activationPolicy of NSApplicationActivationPolicyRegular.
Once the array is filtered, you can search it, using bundleIdentifier, bundleURL, or localizedName to find the app you want. Then send hide or terminate as you like to that NSRunningApplication instance.
Apple has a sample project that demos all this, called AppList.
