I don't know offhand what the default layout manager for a JTabbedPane
is, but it sounds as if it might be FlowLayout, with the JList (now)
too big to fit on the same line as the other panel.

I don't know GridbagLayout well - I hate it like poison and never use
it. Have you tried BoxLayout? I tend to use JPanelS with BoxLayout
inside JPanelS with BoxLayout, or BorderLayout for some things, and if
those don't work, I write my own LayoutManager (which sounds more
difficult than it is).
