FLTK is a small C++ GUI toolkit portable to the MS Windows, Linux, and Mac OSX operating systems. fltk4lua is a binding to this C++ toolkit, which allows you to create GUIs from within Lua scripts.
There is a small Getting Started tutorial with some step by step
instructions to building a GUI with fltk4lua, and a list of
available userdata types, functions, and properties, as well as some
information about building this module in the doc subdirectory (and
on the GitHub wiki). Other than that you will have to use the
official FLTK documentation (fortunately the Lua API is very
close to the C++ API), and look at the examples or the source code.
