Here's some JavaScript that will get you started. I have quickly taken it apart from an application i've developed. It may or may not work for you but it will give you a good place to start.
Be sure to checkout the OpenLayers Documentation.

It hasn't been done yet, but it is definitely possible to use OpenLayers.Popup which does a google-style popup dialog on the map. I haven't tried it myself but I have seen it done.
