As easy as it gets. Add column classes to widgets with a select box, check whether the widget is the first, and save!
I’ve built this plugin for the Genesis Framework, though it will work with any theme that uses the (old) Bootstrap column classes.
You can also add your own classes through various filters to use this plugin with your theme’s grid framework.
<h4>Compatibility (IMPORTANT!)</h4>
This plugin does NOT add CSS for these columns. It ONLY adds the column classes to your widgets. The actual CSS should be added in your theme.
<h4>Filter: `genesis_widget_column_classes`</h4>
Allows you to change the available column classes
Parameters: <code>array</code> Default column classes. 
Return: <code>array</code> Array of column classes.
<h4>Filter: `genesis_widget_column_classes_capability`</h4>
Change the capability required to modify column classes. 
Since 1.2.2
Default: <code>edit_theme_options</code> 
Parameters: <code>string</code> The default capability. 
Return: <code>string</code> The new capability.
<h4>Filter `genesis_widget_column_classes_select_multiple`</h4>
Allow multiple classes to be selected. 
Since 1.3 
Return: boolean.
You can use these filters inside your theme functions.php file or in a plugin.

Adds shortcodes to easily create columns in your posts or pages.
Sometimes you just need to divide your page into different columns. With this plugin you just select a column shortcode and it will add the column to the page. You can also change the padding of each individual column from the UI.
There are 10 different column widths available from which you can make all combinations:
<ul>
<li>full width (1/1)</li>
<li>half (1/2)</li>
<li>one third (1/3)</li>
<li>two third (2/3)</li>
<li>one fourth (1/4)</li>
<li>three fourth (3/4)</li>
<li>one fifth (1/5)</li>
<li>two fifth (2/5)</li>
<li>three fifth (3/5)</li>
<li>four fifth (4/5)</li>
<li>one sixth (1/6)</li>
<li>five sixth (5/6)</li>
</ul>
A preset stylesheet is included, which you can also overwrite to you liking in your theme’s stylesheet.
