Do not forget that all components in Delphi are the objects. Call Create method to create the component and destruct it by Free method. If the component is a window, set parent window and position. This code showing it:

procedure TForm1.Button1Click(Sender: TObject);
var
  Button: TButton;
begin
  Button:=TButton.Create(Form1);
  try
    with Button do 
    begin
      Parent:=Self;
      Left:=Random(Form1.ClientWidth-Width);
      Top:=Random(Form1.ClientHeight-Height);
      Caption:='Button';
    end;
  except
    Button.Free;
  end;
end;
