Word Custom Toolbar

How could I go about making a custom toolbar in word that once clicked would run a specific macro? Also, is it possible to make some sort of installer that would install this button?

Thanks in advance.

No one?

Sorry but I can't seem to remember how to create the Word
AddIn .dot to attach to every instance of Word as they get
created, but this should help to actually create the .dot file. The
rest is up to you.

VB Code:

Option Explicit
'CREATES A NEW TOOLBAR AND ADDS THE OPEN BUTTON TO IT
'AND DOCKS IT LEFT AND LAST TB ON TOOLBAR ROWS
Private Sub Document_Open()
    Dim oTB As CommandBar
    Set oTB = Application.CommandBars.Add(Name:="MyToolBar").Visible = True
    oTB.Controls.Add Type:=msoControlButton, ID:=23, Before:=1, Temporary:=True
    oTB.Left = 0
    oTB.Position = msoBarTop
    oTB.RowIndex = msoBarRowLast
    Stop
    'UNCOMMENT TO DELETE TOOLBAR
    'Application.CommandBars("MyToolBar").Delete
End Sub
