I got components in layout as I wish to have them. Unfortunately 2nd row doesn't start as expected bellow first one, but directly under it (you can see portion of text draw on panel, should be visible whole).
I know that
toolbar should have height of 60
sidebar where thumbnails goes will be wide 185
rest of the parameters are relative
I tried to move two panels from second row to completely separate panel, but it sort of back-fired as they then did not show at all.

SOLVED ! ! !
Removing gbc.gridheight = 60; did the job. I took it as method to set size in pixels
