Posting to WordPress quickly?

With my previous blog, on Blogger, I slightly edited their BlogThis! feature, and with that was able to click on one of my bookmarks and have a small window pop up that allowed me to post straight to my blog without having to go through any login processes or having to click on “Admin” on my blog.

Is there a way to replicate this with WordPress? Effectively I want a way to be able to open a bookmark and have “Title” and “Post” boxes presented, with a “Publish” button that will send the post to my blog.
