Using AJAX in webpart

[NAT]

I have a DateTime field in a database table.I want to open a window whenever
the DateTime in the table is equal to the current datetime.Something like a
reminder which will popup whenver it is time.I want to use AJAX(Asynchronous
JavaScript and XML ) for this functionality. Also I want to develop it in a
SharePoint webpart which will be deployed on a TEam/Portal site. Can somebody
guide me if it is possible and how should I go about it ?
