  We show how some of the refined tropical counts of Block and G\"ottsche
emerge from the wall-crossing formalism. This leads naturally to a definition
of a class of putative q-deformed Gromov-Witten invariants. We prove that this
coincides with another natural q-deformation, provided by a result of Reineke
and Weist in the context of quiver representations, when the latter is well
defined.
