Twitter Widget Pro Installation – "Create An Application"

I’ve installed the Twitter Widget Pro plugin in wordpress. It tells me I need to setup my Twitter app keys. The link in the settings for the plugin in wordpress takes me to a twitter page asking me to complete 4 fields, but I don’t know what to enter in them. The descriptions under the blanks don’t make sense to me and I’m having trouble finding instructions anywhere. Here’s what it’s asking for, my guess at an answer, and the descriptions…

Name: (Twitter Widget Pro?)
Your application name. This is used to attribute the source of a tweet and in user-facing authorization screens. 32 characters max.

Description: (To list recent tweets on my webpage?)
Your application description, which will be shown in user-facing authorization screens. Between 10 and 200 characters max.

Website: (my website’s url here https://blahblah.com?)
Your application’s publicly accessible home page, where users can go to download, make use of, or find out more information about your application. This fully-qualified URL is used in the source attribution for tweets created by your application and will be shown in user-facing authorization screens.

Callback URL: (my website again?)
Where should we return after successfully authenticating?

Thank you for your help!
Greg
