Nothing shown on panel

I'm working on a program, and someone said I need a wxPanel inside a
wxWindow, or else it looks crappy on MSW. I'm trying to add a wxPanel,
but nothing shows up. If I don't use a wx.Panel, self.logo shows up
fine.

Code:
        self.panel = wx.Panel(self, -1)
        self.sizer = wx.BoxSizer(wx.VERTICAL)
        self.sizer.Add(self.panel)
        self.SetSizer(self.sizer)
        self.panelsizer = wx.BoxSizer(wx.VERTICAL)
        self.panel.SetSizer(self.panelsizer)
        self.logo = wx.StaticBitmap(self, -1, wx.Bitmap(LOGOFILE,
wx.BITMAP_TYPE_PNG))
        self.panelsizer.Add(self.logo)
        self.panel.Layout()
        self.Layout()
