Magento: programmatically change widget configuration

I want to change and save the widget configuration from the widget code. I am looking for something like this:

class My_Module_Block_Widget
    extends Mage_Catalog_Block_Product_List
    implements Mage_Widget_Block_Interface
{
    // ...
    protected function _beforeToHtml()
    {
        // ...
        if(/* data needs to be changed */)
        {
            // assuming "widget_config_data" to be one of the widget's
            // parameters configured in the etc/widget.xml file of my module
            $this->setData("widget_config_data", "New Data");
            $this->save();
        }
        // ...
    }
    // ...
}

Since widgets are not models, they do not have a save () method. So how can I save the changed data of my widget?

It will be difficult, and probably more important, that one question is about stack overflow. Here is some background for you to get started. The class / object you are dealing with above is a block class. Blocks are used for rendering HTML. They, as you have already noted, are stateless.

The block gets its data from the widget instance model object.

Mage::getModel('widget/widget_instance');
Mage_Widget_Model_Widget_Instance

The state of these objects (the data you are trying to change) is in the table widget_instance

    <block type="cms/widget_page_link" name="48fc761f38fa9838fcc3a3b498c47f72" template="cms/widget/link/link_block.phtml">
        <action method="setData">
            <name>anchor_text</name>
            <value>asdfasdfsad</value>
        </action>
        <action method="setData">
            <name>title</name>
            <value>asdfasdfasdfasd</value>
        </action>
        <action method="setData">
            <name>page_id</name>
            <value>2</value>
        </action>
    </block>
</reference>
