For g_hbond, you need a .tpr file, which is the run input file for a GROMACS MD 
simulation.  You will need to go through the process of generating the topology 
(pdb2gmx), building the corresponding system (genbox, genion), and build the 
.tpr file with grompp.

Sounds like a good time to learn how to use GROMACS through tutorials :)
