Hello. I am new to Mathematica and currently learning its syntax.

The below commands generate a rectangle, circle and radio button bar control.

My question is how do I encorporate the below commands to get a window area showing the radio button bar so that when you press one of the buttons it will draw the appropriate shape.
I understand that an "If" command is needed but do not know what to put all this in to get the final result.

Many thanks in advance

box = Graphics[{Thick, Green, Rectangle[{0, -1}, {2, 1}]}];(*Rectangle definition*)

oval = Graphics[{Red, Disk[]}];(*Circle definition*)

shape1 = Row[{"Shape Type: ", Control[{{bt, 1}, {1 -> " Rectangle  ", 2 -> " Circle  "}, ControlType -> RadioButtonBar}]}];(*Radio button bar definition*)
