wxWidgets Python save checkbox and other elements values in a text

How to save (and restore) the values of the graphical elements of the wxWidgets in Python? I want some more friendly way, maybe using a for to scrape all the elements and save the current value in a txt when I close the window and restore when I load the app. I do not want to typing 2 line of code (save and restore) to each new element that I add.
