we can create products with custom options by programming in Magento follow the steps :

1. Create a form to submit all mandatory details to create a products

2. Post all details to form controller to save product

   public function saveproductAction()
    { 
    $param            =   $this->getRequest()->getPost();
       $categoryId        =   $_REQUEST['catId'];
       $productName   =   $_REQUEST['ProductName'];
       $productDesc   =   $_REQUEST['productDesc'];
       $productPrice  =   $_REQUEST['productPrice'];
       $productQty        =   $_REQUEST['productQty'];
       $options       =   array();
       $option            =   array();
       for($i=0;$i";
           $options[$j]['title'] = $param['choicetitle'][$i][$j]['title'];
           $options[$j]['price'] = $param['choicetitle'][$i][$j]['price'];
           $options[$j]['price_type']    = 'fixed';
           $options[$j]['sort_order']    = '1';
           }
   
       $option[$i]['title']      = $param['choicetitle'][$i]['choice'];//adding no of choices
       $option[$i]['type']       = $param['choicetype'][$i]['type'];
       $option[$i]['is_require'] = 0;
       $option[$i]['sort_order'] = $i;
       $option[$i]['values']     = $options;
       }
       $newproduct    = new Mage_Catalog_Model_Product();
           $newproduct->setTypeId('simple');
           $newproduct->setWeight(10);
           $newproduct->setVisibility(Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH);
           $newproduct->setStatus(1);
           $newproduct->setSku($productName.time());
           $newproduct->setTaxClassId(2);
           $newproduct->setCategoryIds($categoryId);
           $newproduct->setWebsiteIDs(array(1));
           //$newproduct->setStoreIDs(array(1));
           $newproduct->setStockData(array(
           'is_in_stock' => 1,
           'qty' =>$productQty,
           'manage_stock' => 1
           ));
           $newproduct->setAttributeSetId(4);
           $newproduct->setName($productName);
           $newproduct->setDescription($productDesc);
           $newproduct->setShortDescription($productDesc);
           $newproduct->setPrice($productPrice);
           $newproduct->setProductOptions($option);
           $newproduct->setCanSaveCustomOptions(true);
           try{
           $newproduct->save();
           //echo "Success";
           $this->_redirect('manager/account/dashboardedit/');
           }
           catch (Exception $e){
           echo $e->getMessage();
         }
   
    }
   

   By using this code we can add SELECT, CHECKBOX, RADIO type options to product
