2 language admin

I have looked at a lot of bilingual solutions in WordPress via Google, have not found this:

I have a German language wordpress project. All users will be posting in German. But I am not fluent in German and need the Admin for setting up the blog and adminitration to be in English.

It is fine to get into bilingual wordpress, but my main concern is to have an admin that can switch between German and English. Is that posted anywhere, any plugins, or ??

thanks
