Radio Button in Dialog Box without UserForm

I can't figure out how to use radio buttons for user input rather than typing in responses like I have below. I'd like the user to click on one of the four choices rather than typing them in. Thanks so much of your help!!!

Dim lw As Long
Dim cell As Range
Dim InputValue As String

   lw = Range("A" & Rows.Count).End(xlUp).Row
   Range("D1:D" & lw).Select
   
 On Error Resume Next
   InputValue = InputBox("1-1 FW Entrance" & vbCr & _
   "1-2 FW Exit" & vbCr & _
   "2-1 Hovley Entrance" & vbCr & _
   "2-2 Hovley Entrance II" & vbCr & _
   "3-1 Hovley Exit", _
   "Enter Location")
   For Each cell In Selection
   
   If IsEmpty(cell) Then
      cell.Value = InputValue
   End If
Next
End Sub
