array of page titles to choose

i would like one of the tabs to show a p[lace chosen in the options page. i am trying to mimic the process by which you can choose what category will appear in what section of the front page.

for that specifically i am using this code:

$categories = get_categories('hide_empty=0&orderby=name');
$wp_cats = array();
foreach ($categories as $category_list ) {
       $wp_cats[$category_list->cat_ID] = $category_list->cat_name;
}
array_unshift($wp_cats, "Choose a category");

array( "name" => "Tab #3 category",
	"desc" => "Posts from this category will be shown on the Tab 3",
	"id" => $shortname."_tab_cat_3",
	"type" => "select",
	"options" => $wp_cats,
	"std" => "Choose a category"),

however, i have been running around the codex for a couple of days and i’m not really sure how to proceed. wp_dropdown_pages gives a dropdown (obviously) but no submit – i can’t wuite figure out how to use wp_list in this situation…

i dunno

can anyone get me started?
