ROOT, TTree/TNtuple instead of NTUPLE in GEANT3

Dear Rene and roottalkers,

I am a beginer of using ROOT and I would appreciate if you give me an instruction about
whether it is possible to arrange ROOT TTree/TNtuple output in my FORTRAN program for the
detector simulation using GEANT3 package (using interface or .....) ?

Or, what would be your suggestion to me if there is program written in FORTRAN and I want to use ROOT TTree/TNtuple ?

Thank you in advance,
Rafael
