Tell me good people)
There are several programs on .py, I want to connect it with PyQt for Linux and Windows.
How to design is more or less clear, but how to connect with the code is not clear.

Answer 1

In so, for example, and add:
#! /usr/bin/env python
# -*- coding: utf-8 -*-
# The program shows an empty window that has the basic
# functions of resizing,
# minimizing, maximizing:
import sys
from PyQt4.QtGui import * # interface components
# Each the application must create a QApplication object
# sys.argv is a list of command line arguments
application = QApplication(sys.argv)
# QWidget is the base class for all user interface
# objects; if you use a widget constructor
# without a parent, this widget will become a window
widget = QWidget()
widget.resize(320, 240) # resize the widget
widget.setWindowTitle(u"Hello everyone!") # set the title
widget.show() # show the window on the screen
sys.exit(application.exec_()) # start the main application loop
