您可以通过创建的实例来创建子窗口Toplevel。有关更多信息，请参见http://effbot.org/tkinterbook/toplevel.htm。
这是一个示例，允许您通过单击按钮来创建新窗口：
import Tkinter as tk
class MainWindow(tk.Frame):
counter = 0
def __init__(self, *args, **kwargs):
tk.Frame.__init__(self, *args, **kwargs)
self.button = tk.Button(self, text="Create new window",
command=self.create_window)
self.button.pack(side="top")
def create_window(self):
self.counter += 1
t = tk.Toplevel(self)
t.wm_title("Window #%s" % self.counter)
l = tk.Label(t, text="This is window #%s" % self.counter)
l.pack(side="top", fill="both", expand=True, padx=100, pady=100)
if __name__ == "__main__":
root = tk.Tk()
main = MainWindow(root)
main.pack(side="top", fill="both", expand=True)
root.mainloop()
