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

This contact widget comes with microdatas & microformats markup, so that search engines can use it in their search results. They can help display contact information about your business or yourself below your website in search results, and even a map with your location, to improve your local SEO.
The telephone & email are linked so that visitors can click on it and make a call (through mobile or skype) or send a mail from their computer or their mobile devices.
You can also display a static image map of your location, linking to the address’ Google Maps page, and display a download link for a vCard.
