How do I create a popup window for Twitter authorization?

Question

I want to create a Blackberry Playbook webworks app that links to twitter using an oauth library. How do I create a popup window from within the app using Javascript to display the Twitter authorization page?

It doesn't seem that I can use an iframe, as Twitter's code seems to check if it's running from an iframe, from what I've read.

Answer 1

It doesn't seem to be possible, but via this question I found an extension from polarmobile that does the job. There's also an app called Lemma that demonstrates how to use it.
