Agora vendo seu código acho que a idéia do list te dê muito trabalho.
Eu não estou muito certo disto, pois não tenho como testar daqui, mas dá uma olhada neste comando:
So para esclarecer a idéia do list que vi segue um codigo de exemplo:
cada “linha” do List corresponde a um Contato com as infomãções: String name, String email, Image pic… o resultado fica bem legal na tela:

Aqui http://lwuit.blogspot.com/2009/09/new-components-in-lwuit.html tem outro exemplo de tabelas com WLUIT usando DefaultTableModel
Espero que te ajude.
