This already can be done now, albeit a bit clumsily. See
$ROOTSYS/test/guitest.cxx.

In current version:

// Change background of fTestButton to green
SetWindowAttributes_t wattr;
wattr.fMask = kWABackPixel;
gClient->GetColorByName("green", wattr.fBackgroundPixel);
gGXW->ChangeWindowAttributes(fTestButton->GetId(), &wattr);

In new version:

// Change background of fTestButton to green
ULong_t green;
gClient->GetColorByName("green", green);
fTestButton->ChangeBackground(green);

gtestButton is a TGTextButton.

Cheers, Fons.
