How can I include radiobuttons to a view's results?
Is it very important to you to have radio buttons exactly like you describe? If not, I can recommend the Views Bulk Operations (VBO) module. VBO is a popular module which allows you to select views rows and perform a certain action on those rows. Each row gets a checkbox and you select the action to be performed with those rows using a select box. Here is a screenshot to illustrate that:


I think VBO is by far the most mature option available to solve your problem. If you insist on having the radio buttons in your view and you don't mind writing code yourself, have a look at Views Form Field (interesting, but no releases yet), or Create the "View as form" style (work-in-progress in the Views issue queue).
