Then use something like:
Wordpress user dashboard which is standard

Or some really cool Frontend Editor Plugin for WordPress like:
WP User Frontend Plugin – Free Plugin Link

Frontend Post and Media Manager Plugin – $19 Link

NOTE:Users accounts Must be Author or higher to display the WordPress Add media button

I have a site that i required this as well.
I managed to figure it out.

Edit media-upload.php
Just after line 27 being the following line $settings = youtubeuploader_get_settings();

Add the following lines

// Hack Dev Key request for all users
$DevKey = 'INSERT YOUTUBE DEV KEY';
$settings['developerKey'] = $DevKey;

This will save the You Tube Development key for all users
