Put app.setup() somewhere after app=dabo.dApp() but before the createForm call.

No, you are consulting the correct place.

No need to be sorry.
There's really a 3-stage dApp instantiation process:
1) create the app:
app = dabo.dApp()
2) set up the app:
app.setup()
3) start the app event loop:
app.start()
The setup() call is where the UI library's app object (wx.App) gets hooked into
Dabo's (dabo.dApp). Before setup() is called, there's no wx.App instantiated,
hence
the error you got.
There are other ways to implicitly get dApp.setup() to run, but I think it is
clearer
to just remember the 3 steps above.
