[Interest] Translating Qt (and Qt Linguist) to danish

[scootergrisen]

Hi i would like to start translating some part of Qt to danish (da) 
language.

I can't seem to find who worked on the translation before.

I translate other software like SMPlayer that seems to use files like 
qt_*.qm and qtbase_*.qm so i'm guessing i need to translate qt and 
qtbase so that SMPlayer can be fully translated.

linguist does not even appear on "da" 
http://l10n-files.qt.io/l10n-files/ why is that?
I see linquist under languages like "cs" and "de", but not "da".
