Show WooCommerce Variable Product Options

I am trying to create a query that displays products and some information about them.

I am stuck on showing their variable product options (they will all be variable products). After this I have to create an add to cart button that will add to cart, produce a success or error message, and let the user continue shopping. Once there is something in the user's cart I would like to then display a checkout button that will take them to the checkout page.

Here is what I've got so far

                <?php
                    $args = array(
                        'post_type' => 'product',
                        'posts_per_page' => 12,
                        // Indicate the product category - in this case "Jugs"
                        'product_cat' => 'training'
                        );
                    $loop = new WP_Query( $args );
                    if ( $loop->have_posts() ) {
                        while ( $loop->have_posts() ) : $loop->the_post();

                            // Show the product Featured Image and gallery images
                            woocommerce_show_product_images();

                            // Show the product Title
                            echo the_title();

                            // Show the product Custom Fields
                            echo get_post_meta($post->ID, 'Description', true);
                            echo get_post_meta($post->ID, 'Specifications', true);
                            echo get_post_meta($post->ID, 'Video', true);

                            // Show the Product Price
                            echo $product->get_price_html();

                            // Show the Variable Product options, for example: Color, Size etc 
                            // stuck here!

                            // Show the Add to cart button  
                            // stuck here!

                            // Show the Checkout button if there is an item in the users cart
                            // stuck here!

                        endwhile;
                    } 
                    wp_reset_postdata();
                ?>

Does anyone know the functions I should be using to display this information? I'm having a hard time finding anything about it in the documentation / on google.

Thank you all!!!
