There is no exact answer to this. If you could somehow get a large enough body of water to test it in, many of the gases in Neptune's atmosphere (e.g. ammonia) would rapidly dissolve in the water. Also Neptune is likely to have a dense stony or metallic core under its thick atmosphere, so different parts of Neptune might do different things.
However if Neptune had a homogeneous, insoluble in water, not chemically reactive composition, a sample of it would have a density less than the density of water an so would float, but Neptune does not have such a composition.
