This might be a step up from what you want to do, but NSB/AppStudio might be a suggestion. The IDE is available in 19 languages (Dutch is complete, Danish partially). All the menus, prompts and error message are localized.
It creates apps which run on iOS and Android devices, which makes it more fun and relevant for kids starting out. They can take the apps with them and run them on their iPhone/iPad/iPod/etc.
It uses a programming language with a drag and drop design screen, instead of a cartoon (like Scratch) interface, so it's a more serious tool. Programming languages currently supported are JavaScript and BASIC. (There's some English there, learning keywords, but I don' t think that's so bad).
Runs on Mac or PC.
