There is no canned Help widget that I know of, however you do have a few options.
The first one that comes to mind would be to create a link via the header control widget and add your help instructions in the content area or simply add a link to either a help url or pdf doc on your server. Rob has a good example of a link to an interactive help url site on his: http://gis.calhouncounty.org/ParcelViewer3.0/Help/Default.htm
You could also use Rob's linklist widget to show links to different help topics.
