problem with wxPanel derivation class

[none]

wxGlade created a simple Frame with a panel a sizer and 3 wxControls ,
saticText, TextCtrl, and a Button.

The resulting code works fine.

Now the problem.
I wish to make a separate class derrived from wxPanel that has the sized
and controls as above.  It jusst won't work

It seems as though the complaint is that  a 'wxWindow *' is expected,
'Panel' is received
However, Panel IS a wx.Panel derivative which IS a wx.Window derivative!
Additionally, the methods in the code of Panel and MyFrameOne seem to be
identical.
I can't understand this. Anyone have any thoughts?

I taught myself everything I know about Python and wxPython in the lasst
week and I still don't know everything.
