Packmol is a good choice, but the approach above with genbox likely won't work. 
  It will produce a random insertion of lipids.  The simplest way within Gromacs 
to create a membrane of sufficient size is to place the protein in a suitably 
sized box (with editconf) and then

genbox -cp protein.gro -cs membrane.gro -o protein_in_membrane.gro
