Is there some sort of component that allows me to show a certain page from a normal 
*.hlp file (non HTML) in a form?

Answer:

As far as I know it cannot be done. The closest you can come to it is to take the 
standard WinHelp window and parent it to your form via Windows.SetParent. The 
WinHelp main window has a classname of 'MS_WINDOC', you can use that with 
FindWindow to find its window handle.

1   procedure TForm1.Button1Click(Sender: TObject);
2   var
3     wnd: HWND;
4   begin
5     wnd := FindWindow('MS_WINDOC', nil);
6     if wnd <> 0 then
7     begin
8       Windows.SetParent(wnd, handle);
9       Windows.MoveWindow(wnd, 0, 0, clientwidth, clientheight, true);
10    end;
11  end;
