In what way do they need to?

Anyway, when you create an app, and call its MainLoop, it takes control 
of the, well main loop, and handles the events for everything. I also 
keeps track of if there are any Frames around, and if they are all 
destroyed, the app shuts down.

In short, all the communication required is done behind the scenes for you.

If you do need to explicitly communicate, you can put a reference to the 
frame in the app, a reference to the app in the frame, or use 
wx.GetApp() to get a reference to the app anywhere. Plus other options...
