I have never heard of gretl. How big is the community? And how does it
compare to R, ox and eviews?

It's not that difficult to add a new interaction mode to ESS. The main
problem is not with adding a mode, but rather with maintaining it latter

I can look into it, but not earlier than in a couple of months time.

You can look into it yourself. Sources for inspiration are ess-julia.el,
which you probably should start with, and also ess-r-d.el for a more
complete picture.  Once the editing mode is there, the main step is to
construct ess-gretl-customize-alist with all the defaults needed for the
interaction with the subprocess, and then write 'gretl function for starting
a subprocess.
