rss widget in minamaze

Hi All
I’m using Minamaze theme with http://www.website-development.org and I have installed RSS Feedburner I’ve tried various widget plugins and placed them in every option i.e footers, sidebars etc but to no avail. All i want to do is install a RSS widget I dont really need the other widgets but I dont know how to do it.

Can anyone help please.

Best Regards

Mark
