That depends on what you mean by quick and you won't be able to change the parameter descriptions in the parameter table. However for your UI I have seen samples that reference the parameter names to an array that is keyed to a single parameter for the selection of a language. That way all your UI text can change with the selection of a language parameter.
Is that the type of thing you are looking for? I would have to dig around to see the sample with that functionality as I don't typically use it writing GDL for myself. But the concept is fairly simple.

The only way is either not to use old type parameters but rather the UI where depending on the language You can set the different strings showing up in the description, or double, triple or make more (as the no of languages) parameters variants with the proper names in different languages, than make them visible or not via hideperameter command but the parameters must be linked via glob_modpar_name>parameters commands.
