Dear Ali, Actually, it depends on what you would like to study within the GW approximation (GWA) framework.
Roughly speaking, if you have to deal with calculations in big supercells (+/- 100 atoms), or you would like to study the QPE in molecules, then... please wait ! The GW method based on the used of Wannier-like orbitals [ GWW, see PRB 79, 201104(R) (2009) ] for evaluating the polarization propagator should be released soon (this summer anyway). Otherwise, the Sax code ( https://qe-forge.org/projects/sax-project/ ) should help you... This package allows you to compute the GWA electronic AND optical properties.
