Creating SAP Widgets using the yahoo widget engine

The link will guide you step by step through building an SAP Widget. The prerequisites are:

Yahoo! Widgets Engine : The first and the formost thing you will need is the Yahoo! Widget Engine which will interpret the widget code you write and display your widget.
Text Editor : On Windows, but I use NoteTab light, a powerful free text editor.
Image Editor : Though there are a lot of image editors lying around, I use GIMP (GNU Image Manipulation), for Windows. The price is right, but it does have an unconventional user interface which may lead to steeper learning curves.
The Widget Converter Widget : he use of this widget is twofold. First of all it breaks down flat widgets into its constituent folder structures and files. Secondly it can pack your widget code along with it’s folders into flat widgets. So this is something you surely won’t want to miss.
Yahoo! Widget Engine Reference Manual and other goodies which include a Widget Creation tutorial from Yahoo! can be grabbed from here.
Last but definitely not the least, a little knowledge of XML and Javascript
