How to Display entered Number on the Graphical window

Respected Sir
I Vikas Singhal, working at VECC Kolkata under Subhasis Sir. I am developing a Online Temperature Monitoring System in ROOT environment. Now I am facing some Graphical Problem.
We have created one Main Frame where some radio, check button and Number entry box is present.

Now according to our requirement we have to take data from a file and display on these number entry boxes. After this user can update this data and it should be stored in file.

Problem is we have made main frame and every graphics things but how to Display or modify those numeric values. Question:- How to Display data on Graphical window in Interactive Mode?

Please give solution with example.

Best Regards
Vikas
