Not real, pure gold though UnluckyRaven.
Gold is an element; I'm not referring to wind, water, fire, earth- I mean the periodic elements.
These elements are called elements because they are substances that can not be broken down any further.
Being this, even the combination of the most basic (as broken down as possible) substances can not create because gold is not a compound, it's an element.
It's like saying 1 + 1 = 1...
It just doesn't work that way.
So typically speaking, it's scientifically, virtually impossible.
While as the basics of alchemy are your basic chemistry laws and theories even applying something like nuclear fission (even with the basic alchemic laws not dealing with chemistry) won't create gold out of other substances. Only stars with their massive size and unfathomable amount of pressure causing immense fusion every second of their "life" can do something like that.
