The tutorial is already pointing you in the right direction for this.
If you study the code for the selectFeatures method...

http://docs.geotools.org/latest/userguide/tutorial/map/style.html#what-features-did-the-user-click-on

...you can see that a rectangle (ReferencedEnvelope object) is being
constructed from a mouse click position which is then used in a
filter. You will have a rectangle instead of a click position but can
use the rest of the code from that method unmodified since it already
handles the case of multiple selected features.
