Topic: Is it feasible to create a "start menu" without too much knowledge?

I've been trying to learn javascript and ajax in some of my spare time, and I wanted to do something useful while I learn them.  So I would like to create a "start menu" for an application.  It's just a standard application with tabbed navigation, but I want to add a menu to the bottom-left that operates similar to a windows start menu.  I'm wondering if this is something I should try doing, or if it's too complex/difficult for someone with very little knowledge of javascript/ajax.  The only real experience I have with ajax is using the helpers in RoR to update items, highlight things, collapse, etc.  But my goal is to get a fully-functional start menu, that has links to various pages and the pages would probably still load in the main screen (not going to worry about bringing up little "mini-apps" yet like a normal desktop).  If anyone could give me an estimate of how difficult this would be using just the RoR helpers and very basic javascript, I'd appreciate their input.  Thanks!

You don't even need javascript. You can just use CSS.

It's just a matter of positioning things to make it pop up instead of down.
