I have just downloaded a demo. copy of ComuFoil 3D from the web site and I quite like the program. It has some nice features and is fairly easy to use. CompuFoil 3D is not shareware it is $38.
There are other programs that might be worth investigation too and one of these is by TDM and is called "Airfoil Design Workshop." This may be more what I am after - basically I just wont an aerofoil generator and this program is only $9
I found a web containing links to most if not all of the wing/section generating software available:

I will keep you posted about my new design.
