How to create advanced menu using wp_list_pages() or wp_page_menu()

Hi,

My goal is to have header menu like this:

<ul>
  <li><a href="#"><span>Strona Glowna</span></a></li>
  <li class="multiple">
  <a href="#"><span>Level 1</span></a>
    <div class="ddMenu">
      <ul>
        <li><a href="#">Level 2</a></li>
      </ul>
      <div class="btm"></div>
    </div>
  </li>
</ul>

Could you please give me some tips or solution how to create such forum using wp_list_pages() or wp_page_menu()? Is it possible to create it?

Greetings
