g /: Integrate[g[x_], x_] := q[x]


Integrate[g[z], z]



since you hav not given the correct form fo the function you wish

to integrate, I can only advice to use the most general form of te 
integration, i.e.,

instead of the definition above

Integrate[a_.*g[x_] + c_., x_] /; FreeQ[a, x] := a q[x] + c
