Magento 1 – Load jQuery in Admin Panel Programmatically

adminadminhtmljavascriptmodule

I want to load jQuery in admin panel. How can I do this programmatically without creating layout XML files in /app/design/adminhtml/default/default/layout/? Method with layout XML is described in this thread: https://stackoverflow.com/questions/12799838/how-to-load-a-js-file-on-magento-admin-dashboard

Is there any way to do this programmatically in my custom module?
The module adds some new form fields which can be used on admin pages under System->Configuration. And there I need jQuery to be loaded.

EDIT

In my module I have this custom field in which I need to use jQuery:

class Company_Helloworld_Block_Adminhtml_Mybutton extends Mage_Adminhtml_Block_System_Config_Form_Field
{
    protected function _getElementHtml(Varien_Data_Form_Element_Abstract $element)
    {
        //...here add some custom button functionality
    }
}

You can access the layout programmatically via the getLayout method. Your block class would look something like this

class [Namespace]_[Module]_Block_[Blockname]
{
   public function _prepareLayout() 
   {
      $head = $this->getLayout()->getBlock('head');
      $head->addJs('js/jquery.latest.js');

      return parent::_prepareLayout();
   }

   [...]
}

The issue is almost certainly an incorrect full action name handle. In your controller action you can dump the full action name with $this->getFullActionName().

Alternatively you can inspect the CSS class of the <body> tag and replace the - with _.

Full action name is derived from the router configuration. If you are (as you should be) piggybacking under the adminhtml frontname, your full action name will begin with adminhtml_.

First check if the layout handle is correct.
Add this line in the controller to see the layout handle

echo $this->getFullActionName();

I have a feeling it will print something like this adminhtml_module_sync_index. This is the layout handle you have to use in the layout file.
Also, just to be save, add a name and alias to the block from the content section.
Something like this:

    <adminhtml_module_sync_index><!--put here what you get from the echo in the controller -->
        <reference name="head">
            <action method="setTitle" translate="title">
                <title>Module</title>
            </action>
        </reference>
        <reference name="content">
            <block type="module_sync/adminhtml_index" template="sync/index.phtml" as="index" name="index" />
        </reference>
    </adminhtml_module_sync_index>
