How do you draw this layout with wxpython?

[Young H. Rhiu]

See: http://hilug.org/img/app_layout.GIF

I'm implementing an album-like application with wxpython but I'm new to
wxPython though I know how to program with python. The problem is that
it's not easy for me to deal with drawing layout stuff with wxpython.
What layout I'm thinking of looks like the gif image above.

The application is about saving some comments for each pictures on the
filesystem. There are two windows. The above one is a window for
loading some images and the below one is a TextCtrl for writing
comments and if img1, for instance, is clicked, the first notebook(?)
folder should be active.

Below is the program I tried but I don't know how to attach a notebook
window under the image window.
Any help is greatly appreciated.

Thanks in Advance, Rhiu

My Code:
from wxPython.wx import *

class smallAppFrame(wxFrame):
    def __init__(self, parent, id, title):
        wxFrame.__init__(self, parent = None, id = -1,
                         title = "MySmallApp", pos = wxPoint(200, 200),
                         size = wxSize(460, 200), style =
wxDEFAULT_FRAME_STYLE)

        self.bitmap01 = wxStaticBitmap(self, -1,
wxEmptyBitmap(100,100))
        self.bitmap02 = wxStaticBitmap(self, -1,
wxEmptyBitmap(100,100))
        self.bitmap03 = wxStaticBitmap(self, -1,
wxEmptyBitmap(100,100))
        self.bitmap04 = wxStaticBitmap(self, -1,
wxEmptyBitmap(100,100))

        box = wxBoxSizer(wxHORIZONTAL)

        box.Add((10,10))
        box.Add(self.bitmap01, 0, wxALIGN_CENTER)
        box.Add((10,10))
        box.Add(self.bitmap02, 0, wxALIGN_CENTER)
        box.Add((10,10))
        box.Add(self.bitmap03, 0, wxALIGN_CENTER)
        box.Add((10,10))
        box.Add(self.bitmap04, 0, wxALIGN_CENTER)
        box.Add((10,10))

        self.SetAutoLayout(True)
        self.SetSizer(box)

class MySmallApp(wxApp):
    def OnInit(self):
        frame = smallAppFrame(None, -1, "MySmallApp")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

app = MySmallApp(0)
app.MainLoop()
