wxPython - change panel by button

I would like to write simple code with 2 panels. Simple "Hello" and button next to it. Button changes panel to panel_2 with text "Panel 2" and button next to it. I do not know how can I achieve that. There is my code:

import wx


class Glowne(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent=parent)

        self.SetSize((800,600))

        tekst = 'HELLO'
        font = wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
        wx.StaticText(self, -1, tekst, (300, 10)).SetFont(font)

        btn = wx.Button(self, -1, "Change panel", (345, 100))
        self.Bind(wx.EVT_BUTTON, Program.zmiana, btn)

 class Glowne1(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)

        tekst = 'Panel 2'
        font = wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
    wx.StaticText(self, -1, tekst, (300, 10)).SetFont(font)

        btn = wx.Button(self, -1, "Change panel", (345, 100))
        #self.Bind(wx.EVT_BUTTON, frame.zmiana, btn)



class Program(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY,'Program')

        panel_one = Glowne(self)
        self.panel_two = Glowne1(self)
        self.panel_two.Hide()
        self.SetSize((800,600))
        self.Centre()
    def zmiana(self):
        self.panel_one.Hide()
        self.panel_two.Show()   
if __name__ == "__main__":
    app = wx.App(False)
    frame = Program()
    frame.Show()
    app.MainLoop()

Thank you for any help. I read this tutorial but I can't make it work in my simple code.

Program Frame needs a sizer added, the panels need self added to btn so they can be accesed from class Program, bind to the buttons inside of the class Program.

Here is an example

import wx


class Glowne(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent=parent)

        self.SetSize((800, 600))

        tekst = 'HELLO'
        font = wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
        wx.StaticText(self, -1, tekst, (300, 10)).SetFont(font)

        self.btn = wx.Button(self, -1, "Change panel", (345, 100))


class Glowne1(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent)

        tekst = 'Panel 2'
        font = wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
        wx.StaticText(self, -1, tekst, (300, 10)).SetFont(font)

        self.btn = wx.Button(self, -1, "Change panel", (345, 100))


class Program(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, 'Program')

        sizer = wx.BoxSizer()
        self.SetSizer(sizer)

        self.panel_one = Glowne(self)
        sizer.Add(self.panel_one, 1, wx.EXPAND)
        self.panel_one.btn.Bind(wx.EVT_BUTTON, self.show_panel_two)
        self.panel_two = Glowne1(self)
        sizer.Add(self.panel_two, 1, wx.EXPAND)
        self.panel_two.btn.Bind(wx.EVT_BUTTON, self.show_panel_one)
        self.panel_two.Hide()
        self.SetSize((800, 600))
        self.Centre()

    def show_panel_one(self, event):
        self.panel_one.Show()
        self.panel_two.Hide()
        self.Layout()

    def show_panel_two(self, event):
        self.panel_two.Show()
        self.panel_one.Hide()
        self.Layout()


if __name__ == "__main__":
    app = wx.App(False)
    frame = Program()
    frame.Show()
    app.MainLoop()
