Do business class seats really depend on the aircraft? Doesn't each airline put the seats they choose in each plane?</font>
It depends on the airline. Also, as has been mentioned, the different widths of the planes lead to different configurations. Since the 777 is wider than the Airbus widebodies, typical C-class configuration is 2-3-2 for the Boeing and 2-2-2 for the Airbus.
