done + Gothic?

there is Alb. "gati" , Rum. "gãta ( to finish)", "gata" (ready, done,
prepared, finished), Slavic "gotovo"(Salvic=same meaning?).

I assume this is a loan from Germanic. Old enough if this made the
change of "a" to "o" in Slavic and has the same "a" in Rum. and Alb.
Germ. "tun", eng. "do"; German past part. "getan"= ready, made,
finished.
I don't know exactly if the form in Gothic was "gatan=done, prepared,
made, etc." but a such form will explain all three forms in Rum. Alb.
and Slavic.
The semantism does not need to be explained since this is the same
"done". Any opinions against this loan from a Germanic language which I
suspect to be Gothic?
