Create your own language setup

Great! A Danish translation would be super.

You should do so:
1) Download the current source codes from this site or from Git: https://github.com/Tomark/Katak/.
2) Copy file /i18n/templates/i18n.pot to /i18n/templates/da_DK.po (da_DK is the language code for Danish).
3) Translate the strings labeled msgid, writing the translations on the lines labeled msgstr. You can use a normal edit program, or something dedicated like Poedit (http://poedit.net/). Use UTF-8 encoding.
4) At this point, you should compile (using Poedit) your file obtaining a da_DK.mo file, create the appropriate directory /i18n/da_DK/LC_MESSAGES and place there the file renaming it messages.mo. Then you have to modify the file /include/class.i18n.php, adding your language.
But you can simply send the raw translated file to us (info@katak-support.com) and we'll provide to add the language to the Katak-support program. You can also send a pull request on GitHub. The translation will be published under the Apache and GPL Licenses.

A tip: in a few weeks the new version will be released, perhaps it is better to wait a little and begin the translation of the new one!

We are always happy to assist if you need help.
