QUIC stands on its own; it just so happens that QUIC and SPDY (the predecessor of HTTP/2) show some convergent evolution.
You could use QUIC to transport other L7 protocols, but tracking down generic-enough implementations may be difficult, or at least was the case in the past [1][2]. Maybe things are better now [3].
