Removing default butons

Yayati Ekbote
Hi guys,

I am using Qtopia 2.2.0 and Qt2 designer with the Friendly ARM device to
create my application. But whatever application i make the defalut close
and "OK" button are present. I don;t want those default buttons and want my
own buttons. Is there any way to remove them?? I checked the QWidget flags
but didn't find any for removing the default buttons. Plz guide....
