Is there a way to create a client side tweet using javascript, a textbox, and a submit button? The process would be to enter text to tweet into the textbox, press the button then tweet it using an authenticated account all on the client side.
"Yes".
That said, you need to get an authenticated account on the client side. Twitter does expose mostly RESTful API's for all sorts of things including submitting tweets which you would be able to access via AJAX, however the act of logging in may be difficult due to Twitters reliance on OAuth as a login mechanism. I'm not sure how you could get around that in a totally client-side manner.
I know this isn't exactly what you're asking for, but you can also have users post to Twitter like this:
