Why do you want to use Ada (instead of, say, Python) if you don't like proving things? It seems to me, you might add a book about logic (proof systems etc.) to your reading. I don't know what to recommend. I used "A Mathematical Introduction to Logic" by H. B. Enderton and I liked it, but I think it is not ideal for your purposes. Maybe someone else has a suggestion. If nothing else, understanding what proofs really are might make you more comfortable with them.
