I'm not totally clear on what you want to do. But if you want to create your own popup with your own entries then first read up on the popup module to learn how to create new popup.

Next you need to modify my theme to use the popup you defined. As always there is more than one way to skin a cat, but a simple way is to open script.rc and scroll down to where !QuickLaunchHotspot is defined and change |PopupQuickLaunch to the name of the popup you defined. Then you just need to make sure that the theme settings is set to use Quick Launch for the bottom right corner.
