Yes, the Kendo UI Button can be used to achieve the desired result. There are three aspects of your question:
1. Button size - it depends on its content, so no problems here. I recommend using a <div> tag for the buttons for maximum flexibility with regard to their content.
2. Button styling - if you use the Kendo UI "Metro" or "Metro Black" theme, the Kendo UI Button will have no rounded corners and gradient background. You may only need to override the default background color and apply one of your preference.
3. Button positioning - depends entirely on custom CSS and your preferences
