You need to store the widget ID for the radiobuttons (say in a list).
Then, you could simply index into the list to set the state
of the RadioButton...

e.g.

from Tkinter import *

def Value():
    global CnType, wList
    wList[CnType.get()].configure(state=DISABLED)

def Interface(master):
    global CnType, wList
    CnType.set(0)
    fm5 = Frame(master)
    for i in range(3):
        optTp = Radiobutton(fm5, text='Button %d' %i, variable=CnType,
                            value=i, command=Value)
        optTp.grid(row=0, column=i, sticky=W)
        wList.append(optTp)
    fm5.pack(side=TOP)


root = Tk()
CnType = IntVar()
wList  = []
global CnType, wList
Interface(root)
root.mainloop()


You can get the idea...
