How to include Smilies Popup to a textarea?

[Scandal]

Well, I have a textarea:

<textarea name="myname" id="myid"></textarea>

I want to add a button next to this textarea with smilies popup, so when someone clicks it, it opens the vbulletin's default smilies popup window. When the user click to a smilie, the smilie should added to the <textarea>.
I do some ways but with no result.

An example of the link:

<a href="#" onclick="window.open('misc.php?do=getsmilies&amp;editorid=vB_Editor_001','Smilies' 
,'statusbar=no,menubar=no,toolbar=no,scrollbars=yes,resizable=no,width=430,height=720'); return false;">LINK</a>

What I should add to my template code?

I have stack to the section of the connection of popup with the textarea and also what other I must include to the html code for it to work? I need to input the smilies to the textarea when user clicks to a smilie.

Thanks
