+"MKVMerge GUI" from the "MKVToolNix" package is the right tool for this

+"MP4Box" or the "YAMB" front-end for muxing the audio stream.

+Having said all that, there now is an unofficial "Audio" branch of x264
+available. If you are using one of the patched x264 builds with "audio
+support" patch (e.g. those provided by JEEB), you can process the audio
+with x264 and skip the additional muxing step. Basically the new audio
+patch adds a new "--acodec" switch, which you can pass the x264 as a
+custom parameter. For example you can pass "--acodec aac" for encoding
+the audio to the AAC format (recommended for AAC files). Or you can
+pass "--acodec vorbis" for encoding the audio to the Ogg/Vorbis format
+(recommended for MKV files). Please be aware that audio encoding will
+work only, if your input file contains an audio stream! When using the
+built-in LAVF/FFMS input of x264, the audio can be encoded straight
+from the input file. This does NOT work with Avisynth input! Instead,
+if you want to encode audio from an Avisynth script, you must pass the
+"--audiofile <path_to_avs_file>" switch to x264 as a custom parameter.
+For convenience, the "--audiofile $(INPUT)" parameter may be used.
