Thats easy enough - have you succeeded with this bit - check the
file with a text editor...

Again thats pretty easy, did you get this working - create the file
with a text editior?

No, Tkinter is for building GUIs. Python core language includes
functions for reading and writing to files. Can you do this outside a 
GUI?

Write a program to read the users name and save it to a file.
Write a program to read the file and print the name it finds.
Write a program that says Hello <name> if it finds a name and asks for 
a name if it doesn't.

Now translate that to your GUI.

Yes, it could be in whatever. CSV, XML, ConfigParser or even plain 
text.
