mouse events ?

Question

I am going draw a kind of tree by computer. The input is a text file that has branches' name and length. After drawing tree on screen, user can pick up any branch to remove it. Simply say user can right click mouse on the branch the branch is selected then user can left click mouse and delete the branch. The selected branch will removed from the tree.
Is it can implemented by C#? So user can submit a text file that contain the inforamtion of the tree, then computer draws the tree and user also can remove the tree branches on client site(remove branches by right click it open a delete dialog and then left click to delete it) get a new tree?
Is it possible and how. Thanks
