Advice on GUI development using Drag and Drop

Question

Hi,
 
I'm a VC++ developer finally making the move to C# and have been given an interesting project, to develop an application to view and edit a batch. The application will display boxes each repesenting a job_schedule, and the user should be able to drag a line from one box to another to create a dependency. Double clicking on a job_schedule should open a new window showing jobs belonging to it.
Being new to C# (over 10 years since created a GUI app), I would like to know if I should use WPF or a 'Windows Forms Application'? Are there any controls which would be useful for the GUI?
BTW. It will be a stand alone application (not web app).
Any direction will be greatly appreciated.
Thanks,
Michael
