If you have some php skills to do it, yes it is possible:

Barely any php skills ?? Is the following sufficient or I am far from it?

1) I added a plugin that enables php code execution within post/page.
2) I then created a page with the php code you for querying all the languages (from the link you provided. Thanks! :)).
3) Nothing shows up. Either I did it wrong or?

Thank you for the help ??

That’s probably more complex than that. You have to modify your theme (better to write a child theme). I wrote something quite similar in the past. That’s just a hint to start with, not a complete solution:

Ah. I don’t have the skill to do that. Thanks a lot for replying back :] I will mark the thread as resolved since this will work for people who have more PHP skills.
