I think you rotate the object, but how you connect that to mouse motion, I'm not sure.  There might be something like that in the gear demo that is posted in the sticky.  Can't remember now.

You can do it both ways. I've posted some code in this thread: http://www.jpct.net/forum2/index.php/topic,977.0.html (http://www.jpct.net/forum2/index.php/topic,977.0.html)

The only difference should be that you will need to listen for mouse input from the Applet instance instead of from the Canvas instance.  Of course, it is also possible to use LWJGL in an applet if you want to (using the LWJGL Applet Loader).
