Here is some CODE that i wrote to present the working case.
my main program is split in multiple modules, but this structure should represent what i am trying to get.

module name: multiProcessLauncher.py

import multiprocessing
import gui

def main():
    jobs = []
    p = multiprocessing.Process(target=gui.basicGui)
    jobs.append(p)
    p.start()
    
if __name__ == '__main__':
    main()
    pass


Module Name: gui.py

from Tkinter import *
import tkMessageBox
import Tkinter
import multiProcessLauncher
import action

def basicGui():
    g = action.Action()
    print "GUI"
    processor = multiProcessLauncher
    name = processor.multiprocessing.current_process().name
    print name, "starting"
    print name, "exiting"
  
    top = Tk()
    button = Button(top, text = "Press Me", command = g.do_something)
    button.pack()
    top.mainloop()

def main():
    pass
if __name__ == "__main__":
    main()

Module Name: action.py

class Action(object):
    def __init__(self):
        self.text = "Running Action"
    def do_something(self):
        print self.text

i am trying to figure out how to make use of multiprocessing access the PRINT from the action.py using the GUI button. if you run the code and press the button, the console will read nothing, but as soon as you close the GUI, it spits out the text to console. I read about using Que, but i am not sure how to implement, could someone suggest how? thank you
