There's a bunch of tutorial material linked here 
http://wiki.gromacs.org/index.php/Category:Tutorials. You should get 
familiar with "normal" simulations before you make things complex by 
trying to pull apart your system. There's definitely a NAMD tutorial 
available for AFM pulling on their website, but the details will 
obviously be different.
