QT Replacements for GTK applications on KDE Plasma Desktop?

I haven't used KDE in probably ten years. I've been on GTK desktops ever since. But lately i haven't been happy with them. GTK-3 has made a mess of XFCE. So i've been on Gnome for a while. But i'm not satisfied. Because, well.... it's Gnome. I want to use applications more native to the environment. So for example. on Gnome i was using Simplescan and gedit. and on KDE i'm using Skanlite and Kate.  But what else do i need?  I want to find native QT applications to replace the common Gnome native Applications that i frequently use.  Applications like Gnome online accounts, Gnome contacts, Gnome calendar, Gnome Maps, Gnome dictionary, ect.  Do you have a list of common KDE applications i should be looking at?  Thanks. :)
