NSGradient is, as you say, the key.

Remember that drawing in Cocoa takes place in a view; from that perspective, "Cocoa panel with a gradient background" isn't really a well-formed concept, because it's assuming the panel draws rather than its content view.

So just create your own custom subclass of NSView in which you override -drawRect: to render an NSGradient, and use an instance of it as your window/panel's content view. Or even just put it within your window/panel's content view, covering 100% of its area, with its springs and struts set appropriately.
