A project timeline can be created in Excel using charts linked to data tables, so that the chart updates when you edit the data table. The first template on this page uses a stacked bar chart technique and also includes up to 4 milestones as vertical lines. This template is a cross between my project schedule and task list templates. I've populated the template with some generic product development terminology, but it is designed for you to enter your own tasks and dates. The second template uses a scatter chart with data labels and leader lines to create a more traditional type of timeline.
