Of course.  The GtkScrolledWindow widget can bet set so that the
scrollbars are always on, always off, or automatically shown.

One possible solution is to use the GtkScrolledWindow with the
scrollbars configured not to show, the size set to the minimum proper
size, and then when you pack the widget into a layout, tell it to
"expand" but not "fill."  This way the window has a minimum size, but if
the window is expanded, the plugin widgets will still show properly,
albeit with a bit of whitespace around them.
