Some time ago, I realized that 95.82% of all lists were simple one
dimensional lists in which the user is asked to pick a single item.
I wrote a small set of routines that would handle this case with
the minimum possible effort on the part of the programmer.  If your
list fits this criteria, my library will work.  If not, you're on
your own.
 
If there is much interest, I'll post the source.  If not, I'll mail
it to interested individuals.  I might even have a demo program for
it somewhere.
 
A summary of the routines I wrote follows (I'm writing this from
memory, so it isn't completely accurate):
 
CreateList(ListHdl, WindowPtr, Rect, StringArray, Size)
  Turns StringArray of Size items into a list, and draws it in Rect for
  window or dialog of WindowPtr.  Height of Rect is adjusted to avoid
  truncating the last visible item on the list.
 
UpdateList(ListHdl)
  Call whenever the list must be redrawn
 
ClickList(ListHdl, Item:integer)
  Call when the user clicks in the list or list scroll bar.  Handles
  the action, and returns the cell selected in the variable Item.
