How to display output of a module in a panel?

Hello,

I have writen a module that displays the result of a query.
I am using the hook_menu and I can use the page (or url) correctly.

Now I would like to display the output of my module in a region of a panel.
When I try to add a content to the panel, I do not know how I can add my page (or url).

Do I have to use another hook instead of the hook_menu?

thanks in advance,
Christophe
