Hi Flint

Sure. Try something like this:

Sub CreateToolbarButtons()

Dim oBar As Office.CommandBar
Dim oButton As Office.CommandBarButton

   'MUST tell Word where to save the changes
   'Change this to suit your needs
   Application.CustomizationContext = ActiveDocument.AttachedTemplate

   'Add the toolbar
   Set oBar = CommandBars.Add("MyToolbar")

   With oBar
       'Set the toolbar to be visible
       .Visible = True

       'Add a button
       Set oButton = .Controls.Add(Type:=msoControlButton)

       'Set properties for the button
       With oButton
           .Style = msoButtonIconAndCaption
           .Caption = "My button caption"
           .FaceId = 352
           .OnAction = "MyMacro"
           .TooltipText = "Click here to run MyMacro"
       End With
   End With

   'You'll now need to save the template in which you
   'created the menu bar and buttons

End Sub

Hope this helps.
