Which fonts can i use?

["J. Eusebio Roza Pando" <eusebio roza uah es>]

I use gtk+ for win32, and i would like know which fonts i can use and
what can i called (i only know
"-adobe-helvetica-medium-r-normal--*-100-*-*-*-*-*-*" )
I think that in Linux there is a xfontsel utility but is there this one
in windows?

By the way, in my rc file i wrote:
style "boton_rojo"
{
   bg[NORMAL]={1.0,0.0,0.0}
   fg[NORMAL]={1.0,1.0,1.0}
   bg[ACTIVE]={0.9,0.0,0.0}
   fg[ACTIVE]={1.0,1.0,1.0}
   bg[PRELIGHT]={1.0,0.4,0.4}
   fg[PRELIGHT]={1.0,1.0,1.0}
}
The background changes the color but the label of button (foreground??)
does not change to white, why?

Thanks everyvody for your help,
Cheers !
