Yes, you have to use AddSizer instead of AddWindow. Some overloaded wxLua 
functions are different from what appears in wxWindows documentation; when in 
doubt look at the classes.txt file included in wxLua.

Here is a wxLua example using sizers within sizers:

(see below for the layout building function from the above program)

  bSizer:Add(1, 1, 1)
  -- sizer to hold it all
  local mainSizer = wx.wxBoxSizer(wx.wxVERTICAL)
  mainSizer:AddSizer(hSizer, 1, wx.wxALL + wx.wxGROW, 10);
  mainSizer:AddSizer(bSizer, 0, wx.wxALL - wx.wxTOP + wx.wxGROW, 10);
  -- make layout work
  self.window:SetSizer(mainSizer)
  mainSizer:SetSizeHints(self.window)
  mainSizer:Fit(self.window)
