@Ivan_Svaljek really weird that a dump wouldn’t import without phpmyadmin. Database dump are standards and should be loadable without going through phpmyadmin.
On window, you could try Mysql Workbench. It is a little bit clunky and some options are hard to find, but it works well with ssh tunnelling to remote databases. See this example on how to configure Workbench for remote databases:
if you really want some kind of interface like phpmyadmin, I recommend phpminiadmin which is single file and offer a visual interface. It is less of a hurdle to install than phpmyadmin. It is also easy to remove once you are done.
