It is possible but the process is quite complicated and there is currently no guide available that describes the process and restrictions etc that must be followed for it to work correctly. The widgets themselves are simply standard .xar files that are marked up in a particular way to suit the underlying widget script used (usually JQuery based JavaScript). All the required script files are embedded in the widget .xar file. If you have experience with JQuery then you might like to create a web page that uses a widget, export it and then look at the files generated and open the widget .xar file as a standalone document (it is in the downloaded clipart cache, usually at Local Settings\Application Data\Xara) and examine the markup. This wont help you with various gotchas that occur when making widgets but will give you some idea of how they work.

It is hoped that we will publish a guide to creating widgets (and a basic example widget that can be easily customised) fairly soon.
