How does one distribute Tkinter or Qt GUI apps Developed in Python

[Bruce Whealton]

I watched one training video that discussed Python and Tkinter. Like many similar tutorials from online training sites, I was left scratching my head. 

What seems to be blatantly missing is how this would be distributed. In the first mentioned tutorial from Lynda.com the Tkinter app was related to a web page. However, the browser cannot run Python Bytecode or Python Scripts. 

Surely, one is going to want to create GUI apps for users that are not Python Developers. I would not think to ask someone to install Python on their system and make sure it is added to the path. Maybe it is not so hard for the non-technical, average users. 

I would want to package in some way so that when launched, it installs whatever is needed on the end user's computer. How is this done? 
Are there common practices for this? 
Thanks,
