Looking for a simple Pop menu to code up

Hi,

I just started pocking around Google looking for examples of a simple jQuery popup menu to code up for my website rather than call a webpage to provide the menu which would be slower for the user. If I go the jQuery route, it would need to pop up when I click a button.  The button being clicked to kick it off is in a table so the popup list needs to be more or less centered on the page.  It would have 2 to 5 text items max in alpha order (build by the PHP code when creating the web page) and when the user clicks on one of the items it would automatically kick off a call to another web page. It does not need to be a drop down box because it is so small and probably will never be extended over 5 items. I would be surprised if my website users ask for more than 5 items in the popup. Even if I decide to extend it it would be better if the user entering more items in the database caused the PHP code to build a larger list of items in the popup.  It is probably better if all items are displayed rather than have it be a drop down (faster for the user). I suppose the proper term is a form of "popup list box".  I worked with a series of jQuery popups (popup message, and popup yes/no confirm) just recently and I think I know what I have to do in terms of callback after he user selects an item on the menu in order to call the page. I might add a special menu item to cancel the action and not call the page.

I was looking at this jquery listbox example. 
The problem is I don't know enough about jquery to know if I can get it to popup centered and to have it kick off the page call when the user clicks an item on the list (different actions for different selections if I choose to have a cancel item). Maybe this is too advanced for a low budget (one man does everything) website operation. I have lots of programming experience but very little in jQuery.

Might anyone have any suggestions?

Thanks,
John
