MyBB login screen and user info in WordPress widget

Is it possible to have a MyBB login page embedded in a WordPress widget where the user could supply their info and be logged into the MyBB forum. I want MyBB to do it’s own authentication.

Once logged in, the widget would display their info such as user name, reputation, and other attributes?

I am not looking for any integration of WordPress and MyBB accounts and I do not want any WordPress comments being written to MyBB.

This is simply the same type of info located in the header_welcomeblock_guest template (formatted to fit a widget). And then something very similar to the header_welcomeblock_member template once the login is successful.

The WordPress site is http://www.example.com and the MyBB site is located at http://forum.example.com.

Thank you for any help you can provide.
