Mostly, you need to use a sizer.  Here's one solution that works.  Read the
wxPython style guide:

http://wiki.wxpython.org/index.cgi/wxPython_Style_Guide

especially the section on wx.ID_ANY.  Naming your class ListCtrl is asking
for confusion with wx.ListCtrl.  You need to insert a string item before
you try to set it.  Setting an instance variable outside the instance
(e.g., self.panel.list) is bad form unless there is a good reason for doing
so.  In your program, it isn't even necessary to use instance variables. 
Also read the Python style guide:

http://www.python.org/doc/essays/styleguide.html

especially the section on where to put spaces.

import wx

class MyListCtrl(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Construction d'une liste",
size=(600, 300))
        panel = wx.Panel(self, wx.ID_ANY)

        ##--Creation de la liste
        list = wx.ListCtrl(panel, wx.ID_ANY, style=wx.LC_REPORT)

        ##--Creation des colonnes de la liste
        list.InsertColumn(0, 'column 1', format=wx.LIST_FORMAT_CENTER,
width=400)
        list.InsertColumn(1, 'column 2', format=wx.LIST_FORMAT_RIGHT,
width=200)
        ##--peuplement des cellules
        index = list.InsertStringItem(0, 'cell A1')
        list.SetStringItem(index, 1, 'cell A2')

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(list, 1, wx.EXPAND)
        panel.SetSizer(sizer)

##--Le main Loop
if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = MyListCtrl()
    frame.Show(True)
    app.MainLoop()
