moving from tkinter to wxpython

[Barrowman]

Okay I have now got a little further and just to test it's working it plays a note as the mouse pointer enters a button.
Here is my code so far.
This is a modified version of https://www.blog.pythonlibrary.org/2010/06/16/wxpython-how-to-switch-between-panels/

import wx
import os 
"""
books[0] is used to create 66 buttons in PanelTwo
"""
books = ['67','Genesis050', 'Exodus040', 'Leviticus027', 'Numbers036', 'Deuteronomy034', 'Joshua024', 'Judges021', 'Ruth004', '1 Samuel031', '2 Samuel024', '1 Kings022', '2 Kings025', '1 Chronicles029', '2 Chronicles036', 'Ezra010', 'Nehemiah013', 'Esther010', 'Job042', 'Psalms150', 'Proverbs031', 'Ecclesiastes012', 'Song of Solomon008', 'Isaiah066', 'Jeremiah052', 'Lamentations005', 'Ezekiel048', 'Daniel012', 'Hosea014', 'Joel003', 'Amos009', 'Obadiah001', 'Jonah004', 'Micah007', 'Nahum003', 'Habakkuk003', 'Zephaniah003', 'Haggai002', 'Zechariah014', 'Malachi004', 'Matthew028', 'Mark016', 'Luke024', 'John021', 'Acts028', 'Romans016', '1 Corinthians016', '2 Corinthians013', 'Galatians006', 'Ephesians006', 'Philippians004', 'Colossians004', '1 Thessalonians005', '2 Thessalonians003', '1 Timothy006', '2 Timothy004', 'Titus003', 'Philemon001', 'Hebrews013', 'James005', '1 Peter005', '2 Peter003', '1 John005', '2 John001', '3 John001', 'Jude001', 'Revelation022']

        txt = wx.TextCtrl(self)
 
class PanelTwo(wx.Panel):

    def __init__(self, parent):

        wx.Panel.__init__(self, parent=parent, size=(1180, 520))

            self.btn = 'butt' + str(x)
            btn = wx.Button(self, -1, txt, pos=(column, row ),size=(110, 36 ))
            btn.Bind(wx.EVT_ENTER_WINDOW, self.OnEnterWindow,btn )
            btn.Bind(wx.EVT_LEAVE_WINDOW, self.OnExitWindow,btn )
            btn.Bind(wx.EVT_BUTTON, self.OnClick,btn)
            column += 150
            if column == 1200:

       os.system(cmd)

class MyForm(wx.Frame):
 
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, 
                          "Panel Switcher Tutorial", size=(1200, 550))
        self.panel_one = PanelTwo(self) #,dims)
 
        self.sizer = wx.BoxSizer(wx.VERTICAL)
        self.sizer.Add(self.panel_one, 1, wx.EXPAND)
        self.SetSizer(self.sizer)
 
# Run the program
if __name__ == "__main__":
    app = wx.App(False)
    frame = MyForm()
    frame.Show()
    app.MainLoop()

Obviously I want it to say the word which is on the button but when the button is clicked I want it to display a different set of buttons from 1 to the number of chapters in each book. Which it extracts from the right 3 characters in the books list.
As I am just starting with wxpython I am expecting a steep learning curve.At present I am unsure where to go with it. I guess I could just use a sizer to add 66 panels with the appropriate number of buttons on them or use one panel, clear what's on it then replace them with the correct number. I don't know how to do either right now and don't relish the though of adding 66 panels manually.
However I don't know if it can be done in a loop or if the other option is viable. Any suggestions please?
