Use any of your Contact Form 7 Forms in your sidebars. You can even style it from the widget options. This will also work with any other shortcodes that only work in posts. Just insert the shortcode (ie [contact-form 1 “Contact form 1”]) in the ‘Contact Form 7 tag’ text field. Leave styling options blank in order to style from your theme’s css.
note: rounded corners do not work in Internet Explorer… Surprise! Get a different browser! 
another note: Use 6 digit hex colors for better results
