This plugin is a few years old, and was developed by some guys in China named Xenium and Andot. They no longer have the files available for download on their blog, but luckily, I still have them among my various digital garbage. 
I modified it a little, so it’s not quite the same as it was originally designed. I wrote about it before on my old China blog, and thanks to some comments over there I’ve tweaked it a little bit to make it work a bit better.
You can download the plugin here:
Installation Instructions:
- - Upload the Emoticons folder to your plugins directory.
- - Find this code (most likely on your comments.php page):
-
{textarea id="comment" cols="70" rows="10" name="comment"}{/textarea}Note: Of course “{” and “}” will be “<” and “>” in your code.
- - And just above that, insert this:
if (class_exists('emotions')) {
emotions::bar();
}
?> - - Go to plugin management page in Wordpress, and click Activate Plugin
Keep in mind, I’m not the developer of this plugin, so as much as I’d like to I can’t advise too much if you run into problems. But I do think it’s a cool plugin, and I hope you don’t mind me sharing. To see how it works, see my comment section below.
Update: HelloBMW has a made a GTalk version over on his (Chinese) blog, and I encourage you to check that out as well.

I can’t make this work? The code just shows up as text above the field even after the plugin is enabled.
Also: Aren’t there supposed to be lot more emoji characters?

Are the permissions for the folder set correctly?
i.e. If you put http://www.YOURSITE.com/wp-content/plugins/emotions/images/em69.gif into the address bar, can you see a picture?
