Well that was easy.
Here it is... (sorry for not working on the GUI)

Code:

Public Class Form1
    Dim SW As New System.Diagnostics.Stopwatch
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Enabled = True
        SW.Start()
    End Sub
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Label1.Text = String.Format("{0}:{1}:{2}:{3}", SW.Elapsed.Hours.ToString, SW.Elapsed.Minutes.ToString, SW.Elapsed.Seconds.ToString, SW.Elapsed.Milliseconds.ToString)
    End Sub
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Timer1.Stop()
        SW.Reset()
        Label1.Text = "0:0:0:000"
    End Sub
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Timer1.Enabled = False
        SW.Stop()
    End Sub
    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Timer1.Enabled = True
        SW.Start()
    End Sub
End Class
