ADDIN for Lotus Notes similar to Outllook using DotNet

Hi,

I have a small query, we do know we can have a addin to outlook using DotNet and its very easy to handel the events like send mail and list out all the mails in the inbox and move the selected mails from one folder to another in Outlook. My query is based on this do we have a similar option for Lotus Notes where we can handel the events in the Lotus Notes too. It would be great if someone can answer my query. I work on Dotnet so i wanted to know if we can do it using DotNet. If this is not possible through DtNet then what else can we use to handel those events. And one more thing can we place a user items like buttons and tool bars on the UI of Lotus Notes. It would be great if some one could answer my query
