内置标准库tkinter的用法：

import tkinter as tk
import tkinter.messagebox as msg
 
def winMain():
    win.geometry('400x300')
    win.resizable(False,False)
    wTitle = u'文本框和按钮测试'
    win.title(wTitle)

    initWidget()
    win.update()
 
def initWidget():
    global tEntry
    bX,bY,bW = 80,50,245
    tEntry = tk.Entry(win)
    tEntry.place(x=bX,y=bY,width=bW)
    tEntry.insert(0,'1234567')
 
    bX,bY = 80,120
    bW,bH = 110,50
    bTitle = u'显示内容'
    tBtn1 = tk.Button(win,text=bTitle,command=showText)
    tBtn1.place(x=bX,y=bY,width=bW,height=bH)
 
    bX += 140
    bTitle = u'恢复初始'
    tBtn1 = tk.Button(win,text=bTitle,command=setDefault)
    tBtn1.place(x=bX,y=bY,width=bW,height=bH)
 
def showText():
    global tEntry
    msg.showinfo('显示',tEntry.get())
 
def setDefault():
    global tEntry
    tEntry.delete(0,tk.END)
    tEntry.insert(0,'1234567')
 
if __name__ == '__main__':
    
    win = tk.Tk()
    winMain()
    win.mainloop()
