I dont have the geotoolkit code in front of me (holidays) so the 
following guide might be a bit abstract but should help you.

Every default map objects are created by using the MapBuilder utility class.
MapContext context =  MapBuilder.createContext(DefaultGeographicCRS.WGS84);
The coordinate reference system provided here will only be used when you 
call getEnvelope
on the context, it is not used at rendering time.

The SimpleFeatureTypeBuilder doesn't exist anymore in the latest code, 
it's replaced by FeatureTypeBuilder.

To add a WMS layer you must first create a server :
WebMapServer wmsServer = WebMapServer(serverURL,version)
Then a layer :
WMSMapLayer wmsLayer = new WMSMapLayer(wmsServer, "layerName");

Add it in the MapContext and that's it.

TIP 1 : to quickly verify a MapContext, you can use 
This will display a complete frame, with several map tools, tree, style 
editor ... and so on.
TIP 2 : to render mapcontext as an image use the class 
TIP 3 : the swing map widget class is JMap2D .

We currently don't have much tutorial nor javadoc in geotk-pending so if 
you have ideas for tutorial
feel free to send them on the mailing list.
