I'm not sure you can just add sizers together like that.  When I'm
doing this I'd make panels for each sub-sizer; so input and output
would be panels rather than the sizers themselves.  For example
(untested):

grid = wx.Panel(panel, wx.ID_ANY)

input = wx.Panel(grid, wx.ID_ANY)
inputIco = wx.StaticBitmap(input, wx.ID_ANY, bmp)
labelThree= wx.StaticText(input, wx.ID_ANY, 'Hello')
sz = wx.BoxSizer(wx.HORIZONTAL)
sz.Add((20,20), 1, wx.EXPAND) # this is a spacer
sz.Add(inputIco, 0, wx.ALL, 5)
sz.Add(labelThree, 0, wx.ALL|wx.ALIGN_CENTER_VERTICAL, 5)
input.SetSizer(sz)

output = = wx.Panel(grid, wx.ID_ANY)
label2=wx.StaticText(output, wx.ID_ANY, 'Pease, Quite, Hello, Shalom')
sz = wx.BoxSizer(wx.HORIZONTAL)
sz.Add((20,20), 1, wx.EXPAND) # this is a spacer
sz.Add(label2, 0, wx.ALL|wx.ALIGN_CENTER_VERTICAL, 5)
output.SetSizer(sz)

sz = wx.GridSizer(rows=2, cols=1, hgap=5, vgap=5)
sz.Add(input, 0, wx.ALIGN_LEFT)
sz.Add(output, 0, wx.ALIGN_RIGHT)
grid.SetSizer(sz)

sz = wx.BoxSizer(wx.VERTICAL)
sz.Add(grid, 0, wx.ALL|wx.EXPAND, 5)
panel.SetSizer(sz)
