How to create a self-named text box above the .max file?

Hello, I am a rookie. I don’t know how to create multiple text boxes with initial names that can be set with the GUI. I want to use thrift to transfer data to the Unity client. If it can be above the .max file It is better to display these text boxes, thanks for your help!
CO2box.Text = client.getCO2().ToString() + “ppm”;

If it is difficult to display the text box in the scene, I think it should be simpler to display this on the screen. Can you use the GUI to set a few text boxes on the screen that can be named and set the initial position to call the server data? For example, one of the text boxes is named CO2box and can be called by the above code. I do n’t know how to create this box. This is too difficult for me. I beg you for your help!
