The KDE Frameworks suite solves most of the problems you have to deal with when building Qt applications. It will also integrate perfectly into your Qt projects and the API will be familiar as it is based on the same interfaces that make up the majority of existing Qt applications.

Network Transparency

The increase in connectivity of today's world makes KIO an essential part of your toolset. KIO allows Qt applications to connect to remote shares as if they were on local computers, making accessing server-hosted files and directories transparent and easy for your users. KIO supports ftp, ssh, http, webdav, fish, samba, and many more protocols.
