No, in Czech is not so complicated. There is a PPL courses in English for foreign students in "Flight Academy" and "DSA". I looked at their websites and i have not seen something like that. And if would be like that, i could get it from my country. There is a lot of foreign students who coming to Czech Republic only for PPL, and stay only 2 months.
I didn't know about aerodromes that only offer radio communication in German. I will ask around for more information, if there is no better options for me in Germany, i'll probably go with DSA
