Three-link on Qt?

Question

Qt

Greetings dear Khabrovchan!
I am developing a new project on a new Qt for me. The task is to implement a three-tier architecture for working with the database. Socket communication. The middle and top links will be written in Qt. A solution like WCF in .NET or, at worst, DCOM would be ideal. DCOM itself is not suitable, because need cross-platform.
Unfortunately, I didn’t find anything similar in Qt, but I don’t want to invent another lisaped.
Advise in which direction to dig?
Also, it is necessary to leave the ability to glue all the links in one application, so I plan to use a "sandwich" from QSqlRelationalTableModel and QAbstractProxyModel. Here between them also it would be desirable to transfer the data through a socket if necessary.
