GnuB needs Script-Fu Sensei

I'm very new to Script-Fu,and I need some advice. One of the biggest 
shortcomings I've found to the existing button scripts is that you 
can only produce buttons for one label at a time. I would like to 
write a script that inputs a group of label strings and creates 
identically sized buttons that are all large enough to contain the 
longest label. (This would make them suitable for vertical webpage 
navbars.) For this I need two things:

1.) A "widget" that lets me input a list of strings (preferably as 
lines in a text-box, but I'd accept input from a single-line field 
that was split up by a predetermined delimiter character) that 
returns a string value.

2.) A way to split up the single string into a list of substrings 
using a separator character (newlines for a text-box, some other one 
for a single line input field). Is there an existing function to do 
this?

Once the label input has been converted to a list of strings, it 
should be fairly simple to determine the largest height and width 
required using gimp-text-get-extents-fontname, and build the button 
images later as per Quintero&Aldama's pupi-button.scm script. Later I 
might add some output options that automatically save the images to a 
specified directory under a prefixed version of the label name, but 
that's quite a way down the road.
