请用Python给我写一个程序，程序要求：1：使用Tkinter图形化操作界面，需要创建桌面应用程序界面，图形化操作界面长为1000，宽为800；2：程序拥有计算器功能，可以计算三角函数，通过点击“=”可得出答案；3：程序拥有查询国内所有省、市、直辖市、自治区、自治州、自治县、区、县、村、特区实时天气的功能，可通过在指定的输入框内输入城市名称来查询，并把查询到的信息通过文字形式呈现在图形化操作界面上；4：程序可通过点击“退出”按钮来退出图形化操作界面；5：程序具有访问网页的功能，可通过在指定输入框内输入网址来实现访问网页；6：程序拥有中英文互译的功能，可通过在指定输入框内输入中文或英文并点击“翻译”按钮来实现翻译功能。

好的，下面是Python代码：
