The Widgets module examples is what I am referring to.

The Model View documentation also provides a lot of snippets and depending on the classes of interest, they often link to other examples.

Since you are starting, I would recommend that you start with functionality first and in a second time go with heavy GUI customization.

In the case at hand, you essentially need a QTableView, QPushButton, QLabel and a combo QHBoxLayout/QVBoxLayout.

For your cell custom look, you can implement a QStyledItemDelegate.

As @Renio wrote, Qt's documentation contains quite a lot of examples that you can start from.
