I think your problem is that you call LoadPage before app.MainLoop() is
called, IOW you need to call LoadPage in an event handler:

import wx
import wx.html

class MyHtmlFrame(wx.Frame):
  
    HOME = "http://www.google.co.uk"
    
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, -1, title, size=(600,400))
        self.html = wx.html.HtmlWindow (self)
        if "gtk2" in wx.PlatformInfo:
            self.html.SetStandardFonts()
        self.done_show = False
        wx.EVT_IDLE( self, self.OnShow )
        self.html.SetPage( 
            "<a href='%s'>Loading ...</a>" % self.HOME
          )
      
    def OnShow( self, event ): 
        if self.done_show:
          return
        self.done_show = True
        self.html.LoadPage( self.HOME ) 

app = wx.PySimpleApp()
frm = MyHtmlFrame(None, "Simple HTML Browser")
frm.Show()
app.MainLoop()

Note: the URL you loading takes ages to show, which is why I
use: http://www.google.co.uk above.
