Please make an effort to spell and punctuate like you're a professional 
worth helping ;-)

One approach is to make an .itp file for the peptide (possibly via using 
pdb2gmx on that peptide, and editing the resulting .top file in 
consultation with Chapter 5 of the manual to create a suitable .itp 
file). Generate your starting configuration for your pair of peptides. 
Apply genbox and/or editconf to solvate. Construct a .top file whose 
final [molecules] section resembles
