Show/Hide Buttons Based On Radio Selection

I have a form with three radio options. And I have three buttons:

<input type="submit" name="mainform_action" value="Edit Data">
<input type="submit" name="mainform_action" value="View Data">
<input type="submit" name="mainform_action" value="Delete Data">

If the first radio button is selected, I only want all three buttons to be
visible to the user.

If the second radio button is selected, I only want the "Edit Data" and "View
Data" buttons to be visible.

If the third radio button is selected, I only want the "View Data" button to be
visible.

Is it possible to accomplish this in Javascript? In particular, I want to
continue using the "input type=submit" buttons without having to create my own.
