Assuming that nid = 1 / parentID = 0 is the root.

<?php
$Relationships = array();
foreach($Data as $ID => $Row)
	{
	$Relationships[$ID] = $Row['nid'];
	}

foreach($Data as $ID => &$Row)
	{
	if (0 != $Row['parentID'])
		{
		$Data[array_search($Row['parentID'], $Relationships)]['children'][] = &$Row;
		}
	}

print_r($Data[0]);
?>

outputs ...

Array
(
    [nid] => 1
    [parentID] => 0
    [text] => Dashboard
    [cls] => x-btn-icon
    [icon] => lib/extjs/resources/images/default/icon/Dashboard.png
    [singleClickExpand] => 1
    [leaf] => 0
    [id] => Dashboard
    [children] => Array
        (
