I’ve been using Wt to build apps that directly link to C++ libraries but don’t particularly make a lot of effort to exercise the layout features such as CSS. So far, it works great as a replacement for GTK when building these kind of applications. I’m a Linux user exclusively and I’m also one of the unwashed heathen who actually enjoys programming in C++, and this framework is a perfect way for me to build an application that can actually be used across many platforms.
