If you're talking about Windows Forms applications, "form in form" is normally achieved using MDI, but that would not work well with such a layout.
For tabs there is the TabControl, adding content can be done directly to each page in designer. It would be possible to add a form to a tabpage, but it would be more natural to design such "pages" as usercontrols rather than forms.
