Since molecular dynamics simulations are classical in nature, you, or the forcefield you choose, must set the partial atomic charges. You must also determine your desired protonation states based on the pH conditions you want to simulate.
To actually answer your question, there are programs that calculate what you want, but they are outside the scope of gromacs.
