Wigner matrices Dpq(a) implementation

Dear MathGroupers, 

I'm studying a branch of molecular dynamics, so I need to be familiar
with rotating reference systems, and so son.  Spherical harmonics are
standard in Math, I know,and I've found the additional package about 3D
rotation, but I also need to work  with so-called Wigner matrices
Dpq(a), that are a sort of spherical tensors of rank a=1,2,... 
I'm novice with the argument, but they have almost nothing to do with
Wigner's 3J Symbol ,page 730 of Math3 manual, I suspect.  Has anybody a
reference for a suitable implementation of them,  with all the
necessary combinatorial rules? 
Or at least some easy (as possible) reference texts?  Any suggestion
will be appreciated. Thanks in advance.
