Display a single list item on a SharePoint 2007 page

Question

I've been tasked with becoming a SharePoint guru over night and I need to make a page that displays a single list item in one web part, and related list items (from a second list) in another web part. One requirement for the project is NO custom code is allowed. I can't figure out which web part to use to display a SINGLE list item (as opposed of ALL list items). The page would probably need to get the list item to display from a query string (eg somepage.aspx?ListID=3f04whatever&ItemID=x). Any help would be greatly appreciated. Oh, btw, we're using SP 2007 (in case you couldn't tell from the title).
