There is no such thing, though for Qt-only qmake projects Qt-Creator
comes pretty close.

It does not, designer shows those KDE widgets and that tool has no clue
about code or includes. All it knows about is xml files that describe
gui layouts. If the xml file says a special header file is needed for a
given widget then its the users obligation to setup the project in a way
that this header is found when the generated C++ code is being compiled.

Qt-Creator probably has some GUI to add additional include directories
and libraries to the linking step. I don't know Qt-Creator enough to
tell you how though.
