You can find many answers and examples on site about it.
To create a dialog, you need 2 panels: one is a full screen panel (transparent) which will contain the second panel; this second panel will contain any view you want (a Label and a ListView, in this your dialog).
I remember there's a library that you can display input dialog without radio buttons. You can search Libraries Forum to find it.
Another better way is using XView, I saw many examples with cool dialog. Again, just search Libraries Forum.
