Dear Yuli your question is reasonable, because especially in the dialects of Kosovo theу pronounce it almost the same. The situation is clear at Ç which stands for russian Ч e.g. çka would be pronounced чка and XH which stands for ДЖ e.g. xhepi=джепи. Now unfortunately Q has no equivalent to russian sound but you can imagine a roughly iotacised K. Macedonian Ќ and Czech Ť are quite close but still I think the Albanian Q is more roughly pronounced. Try to pronounce at the same time кйъ/kjë or ть in the word Петька. GJ is almost the same thing with G roughly iotacised. Try гйъ/gjë at the same time or дь in бадья. Although, the best way to realise their difference is to listen native speakers!
