The default background is not white, but transparent for graphics, so there is no sharp contrast. Background -> White makes the background white and leaves borders completely opposite to what you said. BaseStyle does nothing.
This is what I get in Windows XP:

EDIT: An alternative is custom TabView execution on the following lines:
objects = Table[Plot[f[x], {x, 0, 10}], {f, {Sin, Cos, Exp}}]; Column[ {SetterBar[Dynamic[x], Thread[objects -> Range@Length [objects]]], Dynamic[x]} ]
This is not finished, but the basics work, and it shows you how to do it yourself.
