Jumping straight in the deep end is a recipe for frustration. Make sure
you do some tutorial material, and get some practice setting up systems
where you haven't needed to use self-made residue blocks (if you haven't
already). You will need a thorough knowledge of Chapter 5 of the manual.

No, there is no way within GROMACS to generate coordinates of any
structure, apart from adding hydrogens, and such tweaks. The wiki is
currently short of recommendations for molecule builders. Can people
please suggest some?
