No, but experienced quit some pain from some toads once

Poison darts don't have glands but excrete toxins they take up trough food.
Toads and some tree frogs do make poison trough glands.
Altough wild caught dart frogs can still contain poison.

However, try not to touch any type of frog when not needed and always wash your hands before and after working with them.
By the way, before, don't use anything like perfumed soap, it may cause them harm.
