1) to hard to help you with Java Desktop Aplications, because this Framework based on Swing methods is long time depreciated and un_suported, these areas were supported on NetBeans Forums, but looks like as these forums are long time died too,
2) use Standard Swing JComponents, by using Standard LayoutManagers and listening for events by Standard Listeners rather that use Java Desktop Aplications Framework
3) for better help sooner please post here question that contains SSCCE examples for SSCCE,
EDIT
4) in some cases isn't possible directly override basic Swing methods by using this Framework, f.e. starting with to change Java Cup Icon for FrameView

Open the .form file corresponding to your frame (you'll find it in <your_netbeans_projects_directory/<your_project>/src).
It's an XML file, there you can delete reference to jLabel8. But I don't recommend to do that if you feel it's to tricky/risky.
A safer solution you can try is deleting the parent component of jLabel8 and create it again.
