It's outside the scope of GROMACS. If it's just an atom or two, then 
building them in with any old molecule builder is probably acceptable. 
If it's a whole loop missing, then some more high-tech might be in 
order. Google MODELLER and links on their webpage. There are certainly 
web-servers out there that will be able to do things for you, but caveat 
emptor.
