The radiobutton list in each row seems like a good approach because it handles one of your constraints: at most one choice in each row.

To handle the other constraint (exactly one choice in each column) you need to make a handler that's called whenever the selection state of a radio button changes, then check this constraint in the handler. If it's violated (i.e. more than one choice in a column) you can give the user an error message or change their previous selection in that column.

When they're done (e.g. they press the OK button), then you can check to see if every column has a selection.
