custom page in admin area with find posts form

I want to build form in custom page like this:

<form>
<select>select fost 1</select> //open a popup box with posts list, and select first post
<select>select fost 2</select> //open a popup box with posts list, and select second post
<submit> // save the id's in custom table in database,
</form>

I am looking for popup windows with the post that i can select and save them in the form

i found this “Find Posts Dialog Box”: http://shibashake.com/wordpress-theme/find-posts-dialog-box

but every time i select post, that refresh the page and i cant select more then 1 posts like this..

any idea?
