The error

Error:
TypeError: wx.Window, wx.Sizer, wx.Size, or (w,h) expected for item

is showing what is expected.
item = one of the types shown in the error.
widget is a control, all controls/widgets inherit from wx.Window.
Controls are

• Button
  
• Checkbox
  
• TextCtrl
  
• Ect
  

A wx.Panel inherits from wx.Window and can also be used.

Sizers are used for laying out subwindows in a window.
You add (controls/widgets/windows all the same things) and other sizers to sizers.
