I'm trying to create a pop up window to run in the beginning of my program. I am wondering how to make my popup window show once I run my program and how to create a signal slot connection from that popup window to my main window using pyqt4 and qt4 designer?

To start off: I have created a new dialog called popup with two buttons, ok and cancel using qt4 designer. This is the window I would like to make a signal slot connection between the main window and the dialog. Thank you in advance.
