写一个音乐播放器的gui

抱歉，我是AI语言模型，无法提供图形用户界面。以下是一个示例音乐播放器GUI的代码，你可以根据自己的需求进行修改和优化：

from tkinter import *
from tkinter.filedialog import askopenfilename
import pygame

class MusicPlayer:
    def __init__(self, window):
        window.geometry('400x200')
        window.title('Music Player')
        window.resizable(0,0)
        self.music_file = StringVar()
        self.playing = False
        self.paused = False
        self.create_widgets(window)

    def create_widgets(self, window):
        # 标签
        Label(window, text='Select a music file:', font=('helvetica', 12)).grid(row=0, column=0, pady=10)

        # 输入框
        Entry(window, textvariable=self.music_file, width=30).grid(row=0, column=1)

        # 按钮
        Button(window, text='Browse', command=self.browse_file).grid(row=0, column=2, padx=10)
        self.play_button = Button(window, text='Play', command=self.play_music)
        self.play_button.grid(row=1, column=0, pady=10)
        Button(window, text='Pause', command=self.pause_music).grid(row=1, column=1)
        Button(window, text='Stop', command=self.stop_music).grid(row=1, column=2)

    def browse_file(self):
        self.music_file.set(askopenfilename(initialdir='/', title='Select a music file', filetypes=(('MP3 files', '*.mp3'), ('All files', '*.*'))))

    def play_music(self):
        if not self.playing:
            pygame.mixer.init()
            pygame.mixer.music.load(self.music_file.get())
            pygame.mixer.music.play()
            self.playing = True
        elif self.paused:
            pygame.mixer.music.unpause()
            self.paused = False
        self.play_button.config(text='Pause')

    def pause_music(self):
        if not self.paused:
            pygame.mixer.music.pause()
            self.paused = True
            self.play_button.config(text='Play')

    def stop_music(self):
        pygame.mixer.music.stop()
        self.playing = False
        self.paused = False
        self.play_button.config(text='Play')

root = Tk()
player = MusicPlayer(root)
root.mainloop()
