Trouble with Box Sizers in WxPython - python-2.7

Question

I've been trying to produce something that allows me to have multiple sentences in a line.
The code is:
import wx
app = wx.PySimpleApp()
class MyDialog(wx.Frame):
"""
This is my dialog in which I have my interface.
"""
def __init__(self):
"""
This stores all my variables.
"""
wx.Frame.__init__(self, None, -1, "Edit Action", size=(400, 300))
self.my_mini_panels = []
self.my_mini_hboxes = []
self.my_mini_vboxes = []
self.main_vbox = wx.BoxSizer(wx.VERTICAL)
self.main_hbox = wx.BoxSizer(wx.HORIZONTAL)
self.my_mini_panels.append(wx.Panel(self, -1, style=wx.SIMPLE_BORDER,
size=(400, 20)))
self.my_mini_hboxes.append(wx.BoxSizer(wx.HORIZONTAL))
self.my_mini_vboxes.append(wx.BoxSizer(wx.VERTICAL))
self.my_mini_hboxes[0].AddMany((wx.StaticText(self.my_mini_panels[0],
-1, 'Here it is... '),
wx.StaticText(self.my_mini_panels[0],
-1, 'There it was.')))
self.my_mini_panels.append(wx.Panel(self, -1, style=wx.SIMPLE_BORDER,
size=(400, 20)))
self.my_mini_hboxes.append(wx.BoxSizer(wx.HORIZONTAL))
self.my_mini_vboxes.append(wx.BoxSizer(wx.VERTICAL))
self.my_mini_hboxes[1].AddMany((wx.StaticText(self.my_mini_panels[1],
-1, 'Hello, '),
wx.StaticText(self.my_mini_panels[1],
-1, 'Goodbye!')))
for i, hbox in enumerate(self.my_mini_hboxes):
hbox.Add(self.my_mini_vboxes[i])
self.main_vbox.AddMany(tuple(self.my_mini_hboxes))
self.main_hbox.Add(self.main_vbox)
self.SetSizer(self.main_hbox)
if __name__ == '__main__':
dialog = MyDialog()
dialog.Show(True)
app.MainLoop()
It doesn't seem to be working. I'd like it to look like this:
What am I doing wrong?
EDIT
Perhaps I should make it clear that the static text objects must be separate. I can't just replace two segments of text on one line with one larger segment.

You don't need lots of sizers and panels for this. You can use one panel + one sizer + two static text widgets. Here's the code:
import wx
class MyDialog(wx.Frame):
"""
This is my dialog in which I have my interface.
"""
def __init__(self):
"""
This stores all my variables.
"""
wx.Frame.__init__(self, None, -1, "Edit Action", size=(400, 300))
panel = wx.Panel(self)
main_vbox = wx.BoxSizer(wx.VERTICAL)
label_one = wx.StaticText(panel, label="Here it is... There it was.")
label_two = wx.StaticText(panel, label="Hello, Goodbye!")
main_vbox.Add(label_one, 0, wx.ALL, 5)
main_vbox.Add(label_two, 0, wx.ALL, 5)
panel.SetSizer(main_vbox)
if __name__ == '__main__':
app = wx.App(False)
dialog = MyDialog()
dialog.Show(True)
app.MainLoop()
Note also that I changed your app object from wx.PySimpleApp to just wx.App. The wx.PySimpleApp has been deprecated and it is recommended to use wx.App from now on.
You might consider sub-classing from wx.Dialog instead of wx.Frame as that would make more sense if this is really supposed to be a dialog.
