You could use a jQuery tooltip ( Google jQuery tooltip). This is one I found which says that links and images can be shown in the tooltip, but it works on hover, not on click so you have to keep the mouse over the link or tooltip.

You could also use javascript or jQuery to open a popup window with a separate page with links, different page from every link. Here's one example. Click Simple Window Modal.
