This depends on many factors, especially your skills and experience and the complexity of the project you are working on. For the first steps, STM32CubeIDE would be my choice. If you are more adventurous, gcc command line tools, a Makefile, a good editor and register level programming will do fine.

unfortunately , i have 32 bit windows. STM32CubeIDE only support 64 bit widows. i am a beginner of STM32, is there any alternatives for using stm32g4 series with 32 bit windows???

The last (?) version 2.9 of the predecessor System Workbench for STM32 has some support for G4, see https://www.ac6-tools.com/downloads/SW4STM32/. There is a Win32 download, but I haven't used that. In addition, STM32CubeMX may work for chip planning.

Also you can can take EmBitz and configure it for any Cortex-M you need.
