I need a very simple desktop application that logs in my Twitter account, search Twitter for a specific keyword/topic (#topic) and list all Tweets currently referred to that topic. I should them be able to post a reply/Tweet to any (one or more) of the listed messages by clicking on a button aside the Tweet. The messages received/selected shall not be limited to my followers.
The application should be written in Delphi, preferably XE, XE2. Delphi XE provides some nice functions to develop this kind of app, so I assume it is very straightforward job.
