They should be returned by the methods. So you just assign the method
result to a variable:
foo = someModule.SomeClass() # create an instance
bar = foo.someMethod() # call a merthod and store the result.

The result being what? A reference to the new dialog object?
Or the button pressed by the user of the dialog?
For that I would need to know more about Gtk than I do.

It sounds like its the functions and parameter/value passing that you need help
with. The classes aspect is just an extra layer of fog.
Try my tutorial topic on Methods and Functions, see if that helps.
