C++ Desktop Application Help?!?

I am trying to make my own desktop application with C++ on microsoft studio so I don't have to log into my bank every time. It'll be easy access for me and most importantly it'll give me something to do. I started coding not too ago so I thought it'll be fun.

Question is, after writing a simple money transfer program itself, how do I "link" it so that it works concurrently with my bank account bank, which is online as far as I know, either walk-ins or doing it online?

I can write a program and run it so that it can do deposits, withdraws, inputting routing, etc. but how do I "link" it so that the deposits goes into my actual bank account? I hope I am explaining it right....

Using the app venmo or example, how are they able to integrate themselves in a way where their program (venmo app) and our personal bank account work together? How does App (program) ---> Our bank account?

I never have, and never will, log into my bank or Paypal from my phone. I don't use, and never will use, Google pay or anything like it. There is nothing relating to money or my bank stored on my phone, and there never will be. And here you want to make it so anybody who happens by your computer will have complete access to all of your money and assets in a few keystrokes. Have you considered updating Pong as a programming exercise?

Have you considered that if it were that easy to beat the bank security systems the worldwide banking system would have collapsed years ago!
How exactly do you write a money transfer app without access to your bank account!
