You should really check out Stencyl (www.stencyl.com
). It sounds like it fits your needs perfectly.
It uses a visual programming language that is based on Scratch (although not one-for-one). It's gained some attention from educators and has been used by all age ranges (and commercial developers as well). Better yet, you can use it completely for free (if you don't mind a preloader splash screen) to export to Flash - which means easy sharing and playing of the games over the internet. If you want, subscriptions would increase your publishing options as well.
Best of all, to meet your language request, not only are Danish and Dutch translations started (along with, currently, 26 other languages) - you would have the ability to contribute to them yourself to complete the translation. A crowd-sourced translation effort was very recently started (www.stencyl.com/translate
) which already has two completed translations and several others nearing completion. Any user can submit translations and assist with this with no special privileges or permissions required.
In the interests of full disclosure, I am on the forums (as just "Hectate") as a "Master Stencyler" where I have access to the full version of the program due to my extensive support of the community. The role is purely voluntary and I receive no monetary compensation.
Given that it's free, I would really recommend at least checking it out. Please send me a PM (here or there) if you have any questions. Good luck to you!
