Hi Meared,
Web searches on FlowLayout Panel and TableLayout Panel with find examples.
Here are some I found useful.
Many Windows Forms samples to download are available at
http://windowsclient.net/downloads/folders/applications/default.aspx
Search that page for "layout" for a Word document with fairly
comprehensive information about autolayout in the .NET Framework 2.0.
A good blog entry is at
http://blogs.msdn.com/jpricket/archive/2006/04/05/569280.aspx
and an article is at

Below is a fruit basket program I previously posted that illustrates
Combining horizontal and vertical FlowLayoutPanels.
