How to implement window display on click in Qt?

Question

Qt

Hello, I'm new to C++ and Qt, I'm making a program with a graphic to find the roots of a polynomial and some actions on it. I have almost finished and realized that I need to display the solution in a separate window that would appear after clicking "OK", tell me how to do this if I initially made the project a dialog box, and not MainWindow.
Thank you.

Well, what's the problem with transferring it to MainWindow, even just recreating the project and transferring the code?
