How to Embedd a view (filter by the the form input) into the same form (stateless)?

I have a form called Tasks and

Bits I can do:

I would like to create a stateless form that has one drop down box which displays all the the task owners. When the user selects an owner from the drop down box I would like the form...

Bits I can't do:

..to display a list of the tasks where the owner is euqal to the one the user slected in the drop down box. I though this could be done by embedding a view of the tasks which had been filtered dynamicaly, but I am not sure how to do this.

Hope someone can help.
