Adding Language Selector to Menu Bar – Attitude Theme

Dear Attitude Gurus,

I have been searching for a way to add a line of php to the header file (beneath the social icons), to insert a multi-language selector, but it looks like all the header content is being pulled from the database.

Since this does not seem possible without major surgery, I would instead like to add the language selector to the far right side of the main navigation menu bar. What file(s) would I need to edit to be able to do this? Any hints or tips would be greatly appreciated.

Many thanks!
