How do I create a simple C++ calculator app for my desktop?

If you want to keep it simple, libraries like OpenGL and Raylib can help you with the GUI, but for a basic project, I’d recommend sticking with Qt for its straightforward setup. It’s well-documented and great for beginners. Once you get a hang of GUIs with Qt, you can always explore more advanced functionalities later!

First off, make sure you've got a solid understanding of C++. If you're new to it, focus on learning the basics first. Once you're comfortable, start by creating a simple command-line calculator to test your calculation logic. After that, you'll need to pick a framework for the GUI. If you're on Windows, consider using Microsoft's C++/WinRT and WinUI frameworks or look into cross-platform options like Qt or wxWidgets. They're user-friendly and widely used.

Just to clarify, Qt Creator is indeed a graphical user interface for developing applications with Qt. OpenGL and Raylib are more geared towards graphics and game development, so for your straightforward calculator app, Qt would be the best choice. Stick to that for a smooth learning curve!
