You shall read up manual for the structure of topology file.

For your problem, you shall create a top file which contains

#include "ffgmx.itp"
#include "lipid.itp"
#include "popc.itp"
#include "prox.itp"
#ifdef POSRES
; #include "prox-posre-100000.itp"
#include "prox-posre.itp"
#endif
#include "spc.itp"
#ifdef POSRES_WATER
; Position restraint for each water oxygen
[ position_restraints ]
;  i funct       fcx        fcy        fcz
   1    1       1000       1000       1000
#endif
; Include generic topology for ions
#include "ions.itp"
[ system ]
; Name
protein and POPC
[ molecules ]
; Compound        #mols
Protein_X            1
POP 489
