You can use HTML 5 <input> "placeholder" attribute to achive that.
TextBox textBox = new TextBox();
textBox.getElement().setAttribute("placeholder", "some text");
check browser support of this attribute here

For rounded borders just add styleName to TextBox with
border-radius<http://www.w3schools.com/css3/css3_borders.asp>property
