Have a look at the autoform.wlua dialog example:

http://batbytes.com/luafaq/#T6.2.2

The idea is to avoid programming, but declare the fields you wish to
be editable, together with titles and constraints. An example given is
Range(0,4) which will verify that the input is a number between these
values.

I've implemented this pattern with several other frameworks (like
lua-gtk, luajava and Python/Tkinter) so it seems to be generalizable.
