Hi Luis,

Yes, plugins is fine, there is rule that you only can uploade .ui files based plugins.

Yes you can do translation by code.
If you create a test plugin using the Plugin Builder plugin, you get the idea how that is using the Qt translation framework.

See for example here: https://doc.qt.io/qt-5/i18n-source-translation.html
and https://doc.qt.io/qt-5/qtlinguist-hellotr-example.html

So using the 'tr' function instead of hard coded labels for your widgets you should be able to create a <yourlanguage>.ts file (source) and then using Linguist translate those to <otherlanguage>.ts files which you then compile to <otherlanguage.qm> files which should be picked up by your plugin (by pointing to the dir where they are in your plugin. See plugin builder example for that)

HTH
