GUI for wireless testing using iPerf

Write a GUI with the following functions using Python 2.7.x: 1. Drag and drop icons of Wifi devices to locations in room, and use a formula we provide to calculate path loss between devices, and write the results into an array and save it to a file 2. Provide fields for user to enter wifi device IP addresses, paths of iperf and adb 3. Provide buttons that when clicked run commands to start multiple instances of iperf-2.0.5 (one window each wifi router or device) under Windows PowerShell, and run adb commands inside the PowerShell windows. Tests will be for downlink from wifi routers to android wifi devices, write throughput results in each of the Android wifi device into a file and display the throughput results in the GUI
