I don't have seamonky installed, but it seems to be a GTK2 app.
If gtkrc-2.0 doesn't do the job, I don't know what to do.

[rocketmouse at archlinux ~]$ cat .gtkrc-2.0
# Auto-written by gtk2_prefs. Do not edit.

gtk-theme-name = "Adwaita"
style "user-font"
{
	font_name="FreeSans 12"
}
widget_class "*" style "user-font"

Regarding qt5 I have no idea, and as already pointed out, I don't care,
since just the font size always was and still is annoying here, but the
font type is ok.

Did you read man pages and wikis?

[rocketmouse at archlinux ~]$ ls -l /usr/bin/qtconfig*

"GTK+ and Qt
If you have GTK+ and Qt applications, their looks might not exactly
blend in very well. If you wish to make your GTK+ styles match your Qt
styles please read Uniform look for Qt and GTK applications.
Configuration of Qt apps under environments other than KDE Unlike Qt4,
Qt5 doesn't ship a qtconfig utility to configure fonts, icons or
styles. Instead, it will try to use the settings from the running DE.
In KDE or GNOME this works well, but in other less popular DEs or WM it
can lead to missing icons in Qt5 applications. One way to solve this is
to fake the running desktop environment by setting
XDG_CURRENT_DESKTOP=KDE or GNOME, and then using the corresponding
configuration application to set the desired icon set. Another solution
is provided by the qt5ct package, which provides a DE independent Qt5
QPA and a configuration utility. After installing the package, run
qt5ct to set an icon theme, and set the environment variable
QT_QPA_PLATFORMTHEME="qt5ct" so that the settings are picked up by Qt
applications." - https://wiki.archlinux.org/index.php/qt#GTK.2B_and_Qt
