用PyQt GUI写桌面程序

尝试用PYQT写了个windows桌面程序，每次启动时向服务器获取最新的配置信息，更新桌面背景，并检测本地的补丁版本，如果服务端有新的补丁则可以选择更新。

《一》PyQt4安装： https://qa.debian.org/watch/sf.php/pyqt/

注意安装的python是32还是64的，要下对应的版本。

《二》使用PyQt4 designer构建界面:

压缩加壳需要先安装UPX：https://sourceforge.net/projects/upx/files/upx/3.91/

$ pyinstaller.exe  -w -F --icon=wow.ico --upx-dir=C:\Users\test\Downloads\upx391w\upx391w\upx.exe go.py
