How to add ProgressBar to wxWidgets?

Question

User interface

Hey! There is a window code on wxWidgets. You need to add a ProgressBar to it at the very top of the window (of course, not higher than the MenuBar: D).
I went through the Internet and the code of examples, I didn’t find anything (apparently the syntax highlighting in VS2008 makes itself felt) ... Can you please help or at least throw it into Google in Russian .

If the code link doesn't work

#include <wx/wxprec.h>
#ifndef WX_PRECOMP
    #include <wx/wx.h>
#endif
#include "logo.xpm"
class MyApp : public wxApp
{
public:
  virtual bool OnInit();
};
class MyFrame : public wxFrame
{
public:
  MyFrame();
private:
  void OnExit(wxCommandEvent& event);
  void OnAbout(wxCommandEvent& event);
};
enum
{
};
wxIMPLEMENT_APP(MyApp);
bool MyApp::OnInit()
{
  MyFrame *frame = new MyFrame();
  frame->Show(true);
  return true;
}
MyFrame::MyFrame()
: wxFrame(NULL, wxID_ANY, "Окошечко", wxDefaultPosition, wxSize(213, 248))
{
  Centre();
  SetIcon(logo_xpm);
  SetBackgroundColour(wxColour(255, 255, 255));

  wxMenu *menuFile = new wxMenu;
  menuFile->Append(wxID_EXIT, "Выход\t(Ага)", "Просто как бы выход....");

  wxMenu *menuHelp = new wxMenu;
  menuHelp->Append(wxID_ABOUT, "Щто это??7\t(Хз :D)", "Ответ на вопрос \"Что это такое?\"");

  wxMenuBar *menuBar = new wxMenuBar;
  menuBar->Append(menuFile, "&Файл");
  menuBar->Append(menuHelp, "&Помощь");
  SetMenuBar( menuBar );

  CreateStatusBar();
  SetStatusText("(C)Любой Человек");

  Bind(wxEVT_MENU, &MyFrame::OnAbout, this, wxID_ABOUT);
  Bind(wxEVT_MENU, &MyFrame::OnExit, this, wxID_EXIT);
}
void MyFrame::OnExit(wxCommandEvent& event)
{
  Close(true);
}
void MyFrame::OnAbout(wxCommandEvent& event)
{
  wxMessageBox(wxString::Format("Это почти окно\'а\nНо оно ещё без прогресс бара..."),
    "О программе", wxOK | wxICON_INFORMATION);
}
