You really don't want to create a label per udp packet. Take a look at the itemviews.

Hi
Yes you can create QLables dynamically but it gets heavy fast so as Christian-Ehrlicher says,
a model and a ListView is much more fun.
You could try out with a QStringListModel if you dont plan to show millions of rows.

You can see here how to use one.
https://www.bogotobogo.com/Qt/Qt5_QListView_QStringListModel_ModelView_MVC.php

it shows how to add new and remove from the model.

Basically you can place a QListView on the UI form and do

 // Create model
    model = new QStringListModel(this); // its a member
 // Make data
    QStringList List;
    List << "Clair de Lune" << "Reverie" << "Prelude";
 // Populate our model
    model->setStringList(List);
 // Glue model and view together
    ui->listView->setModel(model);

and it will show your list.
