Mixing species is never a good idea but in the past, I have had success with housing red-eye treefrogs and giant day geckos together. My treefrogs and my giant day gecko have been living together for almost three years now without a problem.
I am guesing that it is because the day geck is durinal while the treefrogs are nocturnal so the different species are never awake at the same time to disturb eachother. But maybe I'm just lucky with mixing species... I still don't reccommend that you try it though because you may not be as lucky
