it sounds like you may have more justification for the 170 that just ibm ceasing
support.  the 170 does a much better job of the visual programming, or the 
server apps.

some questions to ask yourself:  is the application you have written already, or
would you be doing it from scratch?  do you have basic experience?  what is your

if your application is already written, you can use visual rpg (either ibm's or
asna's) to create the gui environment.  i haven't used ibm's, but asna's has a
product called datagate that gives record level access to the as/400, and allows
you to do chains, reads, calls directly to the as/400.

if you are going totally from scratch, java may be your best bet.  that appears
to be the future where ibm is going.  this would give you the opportunity to 
users what they want, and learn something new for yourself.

we looked at visual basic several years ago, (before deciding on asna's visual
rpg) ans found it to be a powerful language.  we ended up going with the asna
product because of the direct access to the as/400.
