advanced tabulation

i make me thoughts about a  "advanced tabulation"  package similar to
commercial software products like Quantum or Wincross.

Before i'm beginning to fight with coding - is in the mailing-List anybody
doing something similar in the past and have a good starting point
and/or suggestions for me ?

My purpose ist to define for a dataset  headers (i.e. sex,age-groupes..)
which should write in the colums of a landscape table and percentage all
other
variables ( rows) dependence to the header category !?

P.S. The first attempts sure more easy than
the possibilities in wincross  .......
