They are very different. GMW is a multi-party computation protocol while secret sharing is a technique to distribute a secret. GMW uses secret sharing as a building block but it also uses other primitives like an oblivious transfer (OT). GMW deals with the problem that multiple parties jointly compute a function (over their inputs) securely without revealing anything else except the final output value of the function. Note that a simple difference is that GMW does not have a particular secret distributor (well actually every party distributes secrets), as opposed to secret sharing.

@mallea I would say GMW is based on secret sharing but not solely on that. OT is also a very important component of GMW, which hides the intermediate values when computing the circuit/function.

@mallea, well if Alice and Bob are "distributing shares" to each other, then I'd say it is definitely based on secret sharing. Note that there are 2-party computation protocols (and even >2 party computation protocols) that do not use secret sharing.
