I'm spanish and I can say it, lol. In spain we got "Gonzalo" which sounds the SAME. My irl name is Ignacio xP Though in spain some names have different ways to call them, that's my case and my friends and family call me Nacho because of that.
Gonzalo is not the same has Gonçalo. The "ç" is like a "ss", not a "z". But thats the spanish version of my name :)
