You have to use Cocoa functions directly.

(#/set (#/openHandCursor ns:ns-cursor)) will change the cursor to an open hand.

So, from a listener, you could type
(gui::execute-in-gui #'(lambda () (#/set (#/openHandCursor ns:ns-cursor)) (sleep 3)))

and see the open hand cursor for a few seconds.

It's typical to set up cursor tracking rectangles so that the cursor is automatically updated whenever the cursor enters the tracking rectangle.
