By deriving from MainWindow you invoke the instructor of MainWindow each time you instantiate login.

Thus, your code does:

  1. Make "MainWindow"
  2. "MainWindow" creates login
  3. "Login" inherits "MainWindow" so it makes a new one
  4. New "MainWindow" makes a new "Login"
  5. Reapeat ad infinitum
  6. StackOverflow!

Your "Login" class shouldn't derive from "MainWindow" (and neither should anything else!)
