Well, I've never kept a frog, and the only gouramis i ever had were years ago and they never spawned, but here's the deal.
In nature, any kind of eggs are free protien and just about any creature that can eat them, will do so. So yeah, I'd bet your frog ate them.
On the other side of things, if your gouramis spawned once, they probably will again. I dunno how long it takes before they'd be ready to go again, but if you start seeing signs of bubble nesting, get that froggy outta there! Get anybody else out who could eat the eggs too!
Better yet, maybe you could set up a breeding tank just for the gourami's?
