Hi all i'm new to python and qt

I have played a little with c++ and basic ,But most of the programing I have done in the past was for the web using java script, so this is all new to me.

I am working on a program, and would like to open a window when I push on a button. so fare every thing I have tried has failed. There really doesn't seem to be a good tutorial on this, so I was hoping some would post a simple example of how this is done.

To help with this I have posted three files two are the window files the last one is starting point for the program.

I think other newbies will find this interesting

Thanks for any help
