Answer
Dear Andre,
thank you for your question.
It does sound like they are mating. Since there are two species that are called Grey Tree frog, take a look at these website that explain how to sex both species:

The male will hold on to the female and you should have heard them calling in the last few days. Sometimes males will hold on to each other, but usually only if there are no or too few females around.
I hope I was of some help to you
