I think this is the approach taken by the Titanium project (http://www.appcelerator.com/appcelerator-platform/titanium-architecture/ 
), which allows development using Python, PHP, Ruby, etc.  See for  
example the snippets on their 'codestrong' development site (http://www.codestrong.com/titanium/tutorials/hello-world/?rev=21 
), with constructs like:

<script type="text/javascript"> ... javascript stuff ... </script>
<script type="text/python"> ... python stuff ... </script>

It looks like these can be used to define event listeners as well as  
preparing display content.

There are some core Titanium developers who hang out on IRC and the  
mailing lists who could probably provide better details.

They apparently have some patches to WebKit they will be submitting  
formally at some point (though they are all available in their git  
repository) that provide the language-agnostic support.
