What Portal are you developing one for? I wrote one for IBM WPS and found I needed to have a custom theme to make the portlet work. The issue you may face is that most of the mapping solutions require you to include the map call as part of the HTML body onLoad. When the body of the page is loaded, the map is loaded into the specified HTML container. Google may have provided a hook though that gets you away from having to do this to support portlets. Once you have that solved, it should be very easy to roll out one of your own.
