Is there any form to add another subheader button ?
I need to add another languages on my page, but there is a lot of pluggins in wordpress that translate automatic the texts, and I have my own translate.
I just need to add buttons on the subheader, is it possible?

Pls help

Thanks!

Like what sort of button you want to add? You have a specific area for adding a custom Menu to the subheader, you can add a custom menu there that has links to whatever you need.
