Hi David,
If you check the website
www.football.ch as this is the site for
"FOOTBALL" in Switzerland.
There are small local leagues as well as youth.
Im sure with German you will be fine, it doesnt always have to be Swiss German. If your German is good/ok you should be able to direct yourself around the site and on the pitch.
Otherwise simply contact them directly and see what is possible.

P.S. sorry for the bold writting but this side of the ocean its called football!
