What you're looking at is a custom tile layer. Google requests images
as tiles from your server and displays them over their own maptiles.
It is then up to your server to actually create those images properly
to display whatever you like. When you go to the 'radar' example you
can clearly see the tiles being loaded, one square at a time, because
the "radar" server is much slower than google's server. The tiles are
created by the server somehow to reflect the weather conditions on
those area's.

Setting up a custom tile layer is not very hard on the client side
(but still a bit advanced) and is quite some work on the server side,
depending on what you're trying to accomplish.

Have a look at the GTileLayerOverlay examples.
