Need some advice.

I have a program that is a little fluid but is, for the most part, complete and is approved by the members of my team and management. The program relies on about 10 macro variables that are assigned at the beginning of the program and are used to make decisions throughout the program (dates, datasets, variables of interest etc). The program is intended for an audience that knows very, very little about SAS (or computers in general other than basic dialog boxes and pull-down menus - in other words, basic Windows operations) and rather than me running around feverishly all day long showing users how to change the macro variables to meet their wishes and even having to show them how to open up a SAS session, I would like to create a user interface. I'm willing to and luckily have the time to put in the effort needed in learning to design such a user interface. Not so much asking how to do it as to the best tool to use. I know (or should say knew, since I last used version 4.0) some Visual Basic and was wondering if you could do something like this with VB6 and just create a list box with choices and pass it to SAS. I know next to nothing about SAS/AF or SCL other than the basic ideas. Is it worth investing time and effort in learning? Can I do something like this in VB? Just looking for some good practical advice on how to do this. I've seen some SAS user interfaces but haven't seen one that really impressed me like what VB can do - at least in appearance. Granted, I've never seen one necessarily like I'm sure some of you are experienced in developing. Can anyone suggest the proper route to take. I'd hate to spend three or four months in either learning SCL or SAS/AF and find out it doesn't look right or 'feel' right or appear "Windowy" enough to my users who are computer novices or, alternately, spend that time brushing up on VB and how it can be tied to SAS only to find out it doesn't have the desired capabilities. Thanks very much for any help.
