while loops problem

arg i been at this for a while now.... tring to figure out why is it that when i add a loop in my program the program wont load? or even when i add a for loop i get nothing back

( while loop is in OnInit ( ) )

Code:

class HtmlWindows ( wxHtmlWindow ):

    def __init__ ( self, Parant, ID, frame ):
        wxHtmlWindow.__init__ ( self, Parant, ID )

        self.SetBackgroundColour ( 'Black' )  
    
    def Data ( self, Data ):
    
        self.AppendToPage ( Data )
    

class MyPanel ( wxPanel ):

    def __init__ ( self, Parant, ID, frame ):
        wxPanel.__init__ ( self, Parant, ID )

        self.frame  = frame

        self.html   = HtmlWindows ( self, -1, self.frame )
                    
        
        sizer   = wxBoxSizer ( wxVERTICAL )
        sizer.Add ( self.html, 1, wxGROW )

        subsizer     = wxBoxSizer ( wxHORIZONTAL )
        staticText   = wxStaticText ( self, -1, "Testing" )
        textCtrl     = wxTextCtrl ( self, -1, " " )
        
        subsizer.Add ( staticText, 0, wxGROW | wxALL, 1 )
        subsizer.Add ( textCtrl,   1, wxGROW | wxALL, 1 )
        
        sizer.Add ( subsizer, 0, wxGROW )
        
        self.SetSizer ( sizer )
        self.SetAutoLayout ( True )

        

class MyFrame ( wxFrame ):

    def __init__ ( self, Parant, ID, Title ):
        wxFrame.__init__ ( self, Parant, ID, Title,
                               style=wxCAPTION|wxMINIMIZE_BOX|wxMAXIMIZE_BOX|wxTHICK_FRAME,
                               size = ( 650, 400 ))

        self.Panel  = MyPanel ( self, -1, self )

        self.CentreOnScreen ( wxBOTH )
        
        #wxInitAllImageHandlers() 
        #img = wxImage ( 'folder.gif' )
        #img.LoadFile ( 'folder.gif', wxBITMAP_TYPE_GIF )
        
        self.CreateStatusBar ( 2 )
        self.SetStatusWidths ( [ -1, 150 ] )
        self.SetStatusText ( ctime( time( ) ), 1 )

        Menu     = wxMenu ( )
        Menu.Append ( ID_EXIT, '&Exit', 'Exit The Program' )

        MenuBar  = wxMenuBar ( )
        MenuBar.Append ( Menu, '&File' )
        
        self.SetMenuBar ( MenuBar )

        EVT_MENU ( self, ID_EXIT, self.ExitProgram )

    def ExitProgram ( self, event ):
        self.Close ( True )
        

     

class MyApp ( wxApp ):

    def OnInit ( self ):

        Frame = MyFrame ( NULL, -1, '*:: xlordt ::*' )

        while 1:
            Frame.Panel.html.Data ( 'hmm' )
        Frame.Show ( True )
        self.SetTopWindow ( Frame )

        return True


Win = MyApp ( 0 )
Win.MainLoop ( )

while 1:
Frame.Panel.html.Data ( 'hmm' )

if this is a while True loop, how do you expect it to break;
and if it is not going to break; how do you expect the program to get out of the OnInit method. i think there should be some terminating condition for the while loop
