2. Write Your Code: Start by adding a simple “Hello, World!” message to your application. You can achieve this by using the following code:

“`c++
#include
#include

int main(int argc, char *argv[]) {
QApplication app(argc, argv);

QLabel label(“Hello, World!”);
label.show();

return app.exec();
}
“`
