The developers list is for discussions related to code and GROMACS
development. I am CCing your message over to the gmx-users mailing list,
which is for general GROMACS questions and discussion.

Start with some basic tutorial material. To get what you want, you need
to generate a topology, making use of some existing functional form and
associated parameters (which is the way to get energies) and compute the
energy with mdrun -rerun on your configuration. All of this still
requires you to understand how to generate that topology and assemble a
sensible .tpr file.
