Yes, it is. Since the top level mainloop() only returns when the root
window is closed, you need to change the title it in a callback that's
called in response to some event. I'll append a simple example.

from Tkinter import *

class mainWin:
  def __init__(self,root):
    self.root=root
    self.createWidgets()
    return None

  def createWidgets(self):
    b=Button(self.root,text="Change title",command=self.changeTitle)
    b.pack(side=TOP)
    spacer=Frame(self.root,width=200)
    spacer.pack(side=TOP)
    self.root.title("Test")
    return None

  def changeTitle(self):
    self.root.title("Different title")
    return None
    
def main():
  root=Tk()
  mainWin(root)
  root.mainloop()

if __name__=='__main__':
  main()
