Larger Widget Admin Panel

I am wanting to port a plugin I built for another blog application to wordpress. One of the issues that I am having is the admin panel is really small for all of the options that I offer. I was wondering if anyone had created like a popup screen to utilize then save it from there to provide additional space. Here is a link to the project page that has some pictures of how large the admin panel I am using on that system. http://moviesformyblog.codeplex.com/

I am new to php so any help would be appreciated.
