I'm trying to disable the Qty field on the product edit tab.

I've created a local Mage override of:

app/code/core/Mage/Adminhtml/Block/Catalog/Product/Edit/Tab/Super/Config/Simple.php on line 140 (original):

/* Inventory Data */
    $fieldset->addField('simple_product_inventory_qty', 'text', array(
        'label' => Mage::helper('catalog')->__('Qty'),
        'name'  => 'stock_data[qty]',
        'class' => 'validate-number',
        'required' => true,
        'value'  => 0

And changed it to:

/* Inventory Data */
    $fieldset->addField('simple_product_inventory_qty', 'text', array(
        'label' => Mage::helper('catalog')->__('Qty'),
        'name'  => 'stock_data[qty]',
        'disabled' => true,
        'value'  => 0

I've flushed the cache & still no difference. I've even tried editing the core file itself for testing purposes, and even that makes no difference, even if I completely remove the whole field set addition.

The qty field comes from the template file app/design/adminhtml/default/default/template/catalog/product/tab/inventory.phtml

        <td class="label"><label for="inventory_qty"><?php echo Mage::helper('catalog')->__('Qty') ?><span class="required">*</span></label></td>
        <td class="value">
            <?php if (!$_readonly):?>
            <input type="hidden" id="original_inventory_qty" name="<?php echo $this->getFieldSuffix() ?>[stock_data][original_inventory_qty]" value="<?php echo $this->getFieldValue('qty')*1 ?>"/>
            <?php endif;?>
            <input type="text" class="input-text required-entry validate-number" id="inventory_qty" name="<?php echo $this->getFieldSuffix() ?>[stock_data][qty]" value="<?php echo $this->getFieldValue('qty')*1 ?>" <?php echo $_readonly;?>/>
        <td class="value scope-label"><?php echo Mage::helper('adminhtml')->__('[GLOBAL]') ?></td>

You can change your admin theme and add your own template
