B737-800 Ref Speeds

Hi,
Can anyone explain the relationship between Vspeeds on the 73-800.
Ie I have heard people saying that Vref Flap 40 is equal to V2 Flap 15 or something similar. I am not sure that that is correct.
Is there a definate relationship between all the speeds? If so, how did they design that? Did they choose the area/size of the flaps/slats in such a way that it gave the appropriate speed?
Cheers,
Framer
