I have created a sample app from my real world app. I have used wxPython 3.0, python 2.7 and windows 7 64-bit OS.
The app is simple. It is a GUI with a text field where you can enter an IP address and then upon clicking a button, 10 nslookup queries will be made. The gui.py contains the GUI code and the lookup.py will contain the nslookup process code. After all this I used py2exe to create an executable. I successfully created an executable too.
Problem: When I execute my newly created executable the cmd console also appears/blinks while my app is running and performing nslookup queries! Why is this happening and how to avoid this? However if I execute my app via cmd by typing gui.py and hitting enter, no cmd windows appear during the nslookup process.
Code: All the code and the newly created executable is available for download here, just to avoid any identation problems. Any suggestions will be appreciated.

EDIT: I would really appreciate it if any one of could test my script and post here if you observed any blinking/appearing of cmd console window, while the execution of my python script and as well as during the execution of the executable created.
Solution: I took the suggestion from Mike and finally decided to use socket module instead of nslookup command, and now my problem is solved!
