How to save changes in a custom window?

I have a custom window that allows people to change the texture on the mesh. The problem is when I close the window and reopen it again, it won't save the changes (it will back to the default options). It can be confused sometimes. Does anyone know how to fix that by use python?
Many thanks

Yeah that's mel, it creates a window with two radio buttons. At the top is two procedures one for each button. The state of the radio button is saved until you close Maya.
