Since there's no one generic UI tool that works cross-platform for 
everyone, the first-approximation answer is "can't be done".

Never rely on the first approximation when doing serious work.

First, you'll have to choose which OS's you most need to support.  Let's 
say you only need to support Mac and Unix, and Win32 is not a concern.

Next you're going to have to create duplicate UI functionality for each 
OS.  Let's say that on the Mac you use  MacPerl::Pick and MacPerl::Ask.  
On Unix, you write a similar UI using Perl/Tk.

Implement the UIs as modules, and call them from the common code using a 
conditional test of
"$^O",

If you need to, you may create additional UIs in the same manner.

It's a lot of work, so save it for big important programs.  For quick & 
dirty hacks, I just use STDIN/STDOUT and make a console interface (not 
very Mac-Like, but for light-duty work it's just fine).
