I can definitely vouch for the fact that fish, frogs and newts ( as well as a variety of dragonfly larvae, beetles and others ) will reside happily in the same pond if it is large enough.
The fish do eat the frog spawn as do the newts and both also eat any fish eggs. You can always keep some frog spawn in a separate container until they become tads - gives them a better chance.
If I hadn't inherited my fish, I wouldn't have them in a wildlife pond given the choice but it can be done
I would certainly agree with the above comments that a good depth is vital.....less temperature fluctuations if nothing else.
