Hello All:

I have been thinking to learn develop a GUI using C++.

Any suggestions on where to start? (Using which development kits and etc)

Thank you

Good question, — and good pointers from and about cross-platform toolkits. Since this thread is old, start with modern C++ (C++11 or later) and a current compiler/IDE; many GUI libraries and build tools have evolved since 2007.

Before picking a toolkit, be clear about goals: target OSes, need for native look-and-feel, expected app complexity (simple utility vs full-featured product), distribution model, and license constraints. Those choices determine whether to favour a platform-native API or a cross-platform library that maximizes shared code.

Practical learning path:

  1. Learn the event-driven model: event loop, widget hierarchy, layout managers, and the difference between signals/callbacks and direct method calls.
  2. Build a minimal app (window + one control) and wire an event handler. Use that to explore layout and resizing.
  3. Learn thread rules for UIs: do heavy work off the UI thread and marshal results back to the UI thread via safe events or queued callbacks. Never block the event loop.
  4. Adopt modern C++ idioms: RAII, smart pointers, move semantics, and lambdas for concise handlers. Use a cross-platform build system (for example, CMake) and set up simple CI to test builds on each target.
  5. Add tooling: address sanitizers, static analysis, and platform-specific debugging to catch memory and threading issues early.

Cautions: check the library license before shipping, pay attention to runtime dependencies and ABI/C++-standard compatibility, and test DPI/scaling, fonts, and file-path differences across OSes. Start small: implement a simple tool, iterate, then expand. This reveals the framework's workflow and deployment quirks faster than theory alone.

for cross-patform GTK is a popular choice.

You could also use give Qt or WxWidgets a try, they're also popular choices for cross platform.
