If you don't already have access to a force field for your system 
formatted for use in GROMACS, then you'll have to write/convert your 
own. Extensive reference to Chapters 4 and 5 of the manual will be 
required. You should look around the web and literature for what might 
be available.

It is worth doing some of the tutorial material to get a feel for how 
things fit together in GROMACS, even though they're mostly focussed on 
protein simulations.
