This is not the same approach. Wxwidget is C++ which makes binding to other languages cumbersome. The same applies also to TK which is binded trough an embedded TCL interpreter.

Also TK doesn't offer native looks. Wx tries, though I'm not sure how good taking into account all platforms.

Since version 8.5 Tk ships with themed widgets that by default try to look native on Windows and OS X by leveraging the respective platforms' native GUI toolkits for drawing.

For the details see https://tcl.wiki/14796.

Wx tries, but IMO fails to varying degrees to feel "right". WxGTK in Linux is okay-ish (everyone expects shitty UX from GTK programs anyway); WxMSW is an eye-sore. I haven't dared using Wx under OSX yet.

What makes wxMSW an eyesore? Is it anymore of an eyesore than plain Win32?

Can you elaborate on your points? including this one:
